What is her velocity if it takes her 60 seconds?
Takes her 60 seconds to do what? Travel 1 mile? Travel 10 miles?
What is the velocity of an object that travels 15 meters in 2 seconds?
7.5
What is the average velocity of the particle from rest to 9 seconds?
The answer will depend on its acceleration.
What is the velocity and in what direction at time 9 seconds?
Without knowing some of the conditions that led up to the situation at 9 seconds, I'm afraid there's no way to figure that out. By the way, once you know the 'velocity', you know the 'direction'. 'Velocity' means speed and direction. It's not just a big technical-sounding word for 'speed'.
When a person steps off a 12 foot diving board with 0 intitial velocity how many seconds does it take to reach the water?
0.8633 seconds
What is the deceleration of a car traveling with a velocity of 30 meters per second slowing down to a velocity of 10 meters per second within 10 seconds?
you doing homework???
A braking time of 1.5 to 2 seconds what is the final velocity?
You need more details.The final velocity could be 0However, you need to know the initial velocity, and the braking acceleration, and perhaps other acceleration/deceleration factors to know the true answer.
When throwing a ball straight up when in the air with an initial velocity of 10 meters per second what high will it go and how long will it take to return to the ground?
The initial velocity is 10 meters/sec and is thrown up against the gravitational pull of the earth. This means that the ball is experiencing a deceleration at the rate of 9.8 meters/sec/sec to bring its final velocity to zero. v^2 - u^2 = 2gs where u is the initial velocity, v the final velocity, g is the acceleration or deceleration, and s is the distance traveled. 0^2 - 10^2 = 2 x (-9.8) x s -100 = -19.6s 100 = 19.6s s = 100/19.6 = 5.102 meters Now v = u + gt where v is the final velocity, u is the initial velocty, g is the acceleration or deceleration, and t is the time. When the ball is thrown up with 10 meters/sec velocity it is acted upon by the deceleration of gravity until its velocity becomes zero. So 0 = 10 - 9.8t or 9.8t = 10 t = 1.020 seconds The time for the ball to go up is 1.020 seconds and the same time is taken for the ball to come back for a total of 2.040 seconds.
What velocity does the student have after five seconds?
Velocity increases after 5 seconds
How do you get the velocity?
Velocity is derived by dividing displacement with time in seconds
When an archer shoots an arrow straight up with an initial velocity magnitude of 100.0 ms. After 5.00 s the velocity is 51.0 ms. At what rate is the arrow decelerated?
The change in velocity is 51-100 = -49 m/s This occurred over a period of 5 seconds so The (negative) acceleration - aka - deceleration is (-49 m/s)/(5 s) = -9.8 m/s²
Mary breaks to halt at a speed of 70 meter per seconds in just 2 seconds what is it deceleration?
35/s-2
How many feet to stop a car running at 55 miles per hour?
That depends on its rate of deceleration. And the rate of deceleration depends on the quality of the brakes, the friction of the road and the tires, if it is raining, snowing, black iced, sand, gravel, cement, black top, ect. Lots of variables. But let's say that the deceleration is 5 miles/second squared, to make it real easy. You find how many seconds are in a minute, and how many minutes are in an hour. Let me do the math for you, 60/60/60, now multiply that by our velocity, 55. 60/60/60*55 = .91666667 miles per second. Divide current velocity (.9166666667) by rate of decelration (5 mi/sec squared) and you get your answer in seconds. I just made that problem up. In real life, that sounds incredibly unrealistic. This question would be much more complete if you had the rate of deceleration in the question.
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
A student riding her bicycle on a straight flat road covers one block every 7 seconds if each block is 100m long she is traveling at?
Constant speed and constant velocity
What is the velocity of the object between 20 and 40 seconds?
The velocity = (location at 40 seconds - location at 20 seconds)/20 in the direction in which the object is moving.
What is the duration of WWE Velocity?
The duration of WWE Velocity is 2760.0 seconds.
