Finding the speed of a projectile, such as, a ball is simple considering you know the net force acting on the ball. Another way to go about figuring out this problem would be knowing the exact distance it traveled, most likely a parabolic trajectory excluding air drag, and knowing the time the ball was in the air; then the speed of the ball would be given as D=rt(D denoting distance, r denoting average rate/speed, and t denoting the time the ball was in the air). Back to the first method the equation used in this circumstance would be F=ma, also know as Newton's Second law of motion, and would be easiest excluding air drag. So, a person throws a 145g/0.145kg ball with a force of .5 Newtons to go about finding the speed of the ball in this equation we would use the equation F=ma-.5=.145a-a=3.45m/s2 meaning all you have to do to find the speed of the ball is multiply the value by the number of seconds after the initial thrust. Therefor, .5 seconds after the toss the ball should be-- .5s(3.45m/s2) 3.45(.5)=1.725 and m/s2/s=m/s therefor the speed is 1.725m/s after half a second. Of course after the ball strikes the ground it will be influenced by another natural force imposed by the ground which should be equal to the force that the ball initially retained. Or taking air drag into effect the force would probably no longer have an influence on the balls speed and then be effected by the law of momentum conservation. As of now all we have is a speed for the ball, 1.725m/s, we also want a velocity. To derive a velocity all the information that is needed is to know which direction the force was directed in, lets say 14o North We would now write 1.725m/s 14oN which can be written as a vector.

How do you find speed if you know the velocity?
Velocity is speed and direction
How do you find mass if you are given the momentum and the speed?
momentum = mass x velocity => mass = momentum / velocity
If a ball is thrown into the air with a velocity of 38 ft per sec its height in feet after t seconds is given by y equals 38t minus 16t2 Find the velocity when t equals 2?
Substitute the 2 in for t.38(2)-16(2)^276-64=12
How do you find velocity given only mass and speed?
You can't, because you don't have enough information. In order to find velocity, you need to be able to find the speed and the direction of motion. You have the speed, but you have no information that you can use to determine the direction in which the object is moving. Mass doesn't help.
What formula do you use to find speed acceleration and velocity?
velocity= distance/time=d/t accelaration= dv/dt
How do you find speed if you know the velocity?
Velocity is speed and direction
How do you find the velocity form the speed of a car?
Velocity means speed and direction. So if you know the speed, all you need to add is the direction of motion and you will have the velocity.
What kind of sensor is to detect the speed of velocity?
If you know the velocity you can find the speed, you don't need a sensor.
How do you find the velocity of a ball?
Some channels show you the distance between the ball and the goal at freekicks. They also show the speed of the shot. On average a freekick is between 80 and 100km\h.
A ball thrown up vertically returns to the thrower after 6 seconds find the velocity with which it was thrown up?
The velocity changes from [ V upward ] to [ V downward ].The total change in velocity is [ 2V ].Acceleration = (change in velocity) divided by (time for the change) = 2V/6But the acceleration is just the acceleration of gravity = 9.8 meters / sec2 .9.8 = 2V / 62V = 58.8V = 29.4 meters per second upward
What is the ball's angular velocity A ball at the end of a string of length 0.75 m rotates at a constant speed in a horizontal circle?
A ball at the end of a 0.75 m string rotating at constant speed in a circle has an angular velocity of (2 pi) divided by (time to complete one revolution). Time to complete one revolution = (speed) divided by (2 times pi times radius). If you write this algebraically and then simplify the fraction, you find that the angular velocity is (4 times pi2 times radius) divided by (speed) = (29.609/speed) radians/sec. The speed is expressed in meters/sec. The solution doesn't depend on the orientation of the plane of the circle.
How do you find final speed if acceleration time and beginning velocity is given?
(acceleration X time) + beginning velocity = final speed
What does Calculus means?
In a nutshell, calculus is the mathematical study of change. Algebra covers mainly linear applications like velocity = distance divided by time. Calculus is used to find the instantaneous velocity of a ball thrown 6 feet in the air as it is falling, paused in time at 4 feet up (the velocity is getting faster as the ball comes down, so you need calculus equations and techniques to figure this out).
When a ball is thrown vertically upward at initial velocity of 15 meter per second Find the position and velocity after 1.0 second and 40 second after leaving your hand?
1 sec : position = 10.1 metres above your hand, velocity = 5.2 ms^-1.40 sec : position = 7240 metres below your hand, velocity = 377 ms^-1 downwards.
What is an average velocity of a kicked soccer ball?
you cant find an average, because NO-ONE kicks at exactly the same amount of speed and force as any other person.
How do you find the uniform acceleration if the speed and acceleration are given?
Find out the time using speed and acceleration, (time=speed/acceleration) and then use it to find out uniform velocity. From that find out uniform acceleration. (as uniform acceleration is equal changes of velocity over equal intervals of time)
How do you find mass if you are given the momentum and the speed?
momentum = mass x velocity => mass = momentum / velocity
