If a ball that is freely falling has attained a velocity of 19.6 meters per second after 2 seconds. What is its velocity five seconds later?
A freely falling Ball has the acceleration of 9.8 m/s/s so after 5 seconds its velocity will be: t=5s a=9.8m/s/s v=5s * 9.8m/s/s =49 m/s
An arrow in flight has an initial velocity of 65 meters per second and 10 seconds later it has a velocity of 35 meters per second Which is the acceleration of the arrow?
Acceleration of the arrow is -3m/s2A = (velocity minus initial velocity) / time
What is the final velocity of a stone with an original velocity of 0 falling from a ledge that takes 8 seconds to hit the ground?
On Earth gravity equals 9.8 m/s^2. If you multiply that by 8 seconds you get: 78.4m/s
What is a cars acceleration if it travels 0 to 55 miles per hour in 6 seconds?
Acceleration = Change in Velocity / Change in Time a = (Final Velocity - Initial Velocity) / (Final Time - Initial Time) = (55-0)/(5-0) = 55/5 a = 11 m/s^2
How many seconds does it take to go 30 mph?
Data is insufficient. initial velocity is 0. final velocity is 30 mph. Need acceleration to use the formula v = u + at.
If a ball that is freely falling has attained a velocity of 19.6 meters per second after 2 seconds. What is its velocity five seconds later?
A freely falling Ball has the acceleration of 9.8 m/s/s so after 5 seconds its velocity will be: t=5s a=9.8m/s/s v=5s * 9.8m/s/s =49 m/s
If a car goes in 6.8 seconds how do you figure out the acceleration?
To calculate acceleration, you need to know the initial velocity of the car and its final velocity after 6.8 seconds. The acceleration can be found using the formula: acceleration = (final velocity - initial velocity) / time.
What is the vehicles velocity after 1.0 seconds?
That depends on its initial velocity and its acceleration. V1 = V0 + a * t
How do you calculate the change in velocity of a falling object?
The speed (magnitude of velocity) is always 9.8 meters per second (32.2 feet per second) greater than it was exactly one second earlier. If the object spent "N" seconds falling, then its speed (magnitude of velocity) is 9.8N meters per second (32.2N feet per second) greater at the bottom than it was at the top. The direction of velocity remains constant under the influence of gravity ... straight down.
An arrow in flight has an initial velocity of 65 meters per second and 10 seconds later it has a velocity of 35 meters per second Which is the acceleration of the arrow?
Acceleration of the arrow is -3m/s2A = (velocity minus initial velocity) / time
If a ball thrown straight up climbs for 3.0 s before falling Neglecting air resistance with what velocity was the ball thrown?
The initial velocity of the ball can be calculated using the kinematic equation: v = u - gt, where v is the final velocity (0 m/s at the top of the motion), u is the initial velocity, g is the acceleration due to gravity (9.81 m/s^2), and t is the time taken to reach the top (3.0 seconds). Solving for u, the initial velocity is approximately 29.43 m/s.
While launching a rocket of mass 2 104 kg a force of 5 105 is applied for 20 seconds The velocity attained by the rocket at the end of 20 seconds?
To find the velocity attained by the rocket, we can use the equation: velocity = initial velocity + (acceleration x time) First, calculate the acceleration using Newton's second law: acceleration = force / mass = 5 x 10^5 N / 2 x 10^4 kg = 25 m/s^2 Next, plug the acceleration and time (20 seconds) into the formula to find the final velocity: velocity = 0 + (25 m/s^2 x 20 s) = 500 m/s.
What is the acceleration of car that increase its speed by 10 milessec after 30 seconds if the initial velocity was 20 milessec?
The acceleration of the car can be calculated using the formula: acceleration = (final velocity - initial velocity) / time. In this case, the final velocity is 20+10 = 30 miles/sec, the initial velocity is 20 miles/sec, and the time is 30 seconds. So, the acceleration of the car is (30 - 20) / 30 = 0.33 miles/sec^2.
When acceleration occurs?
Acceleration occurs when velocity changes over time. The formula for it is as follows: a = (Vf - Vi) / t a: acceleration (meters/seconds2) Vf: Final velocity (meters/seconds) Vi: Initial Velocity (meters/seconds) t: Time (seconds)
What is the braking time from 1.5 to 2 seconds what is the final velocity?
To calculate the braking time from 1.5 to 2 seconds, we need to know the initial velocity and the acceleration of the object. The final velocity can be determined using the formula: final velocity = initial velocity + (acceleration * time). If we have this information, we can plug in the values to find the final velocity at 2 seconds.
If a Ferrari with an initial velocity of 10 ms accelerates at a rate of 50 mss for 3 seconds what will its final velocity be?

If a train is accelerating at a rate of 4km per hour per second and its initial velocity is 20km per hour what is its velocity after 30 seconds?
The train's velocity after 30 seconds can be calculated using the formula: final velocity = initial velocity + (acceleration * time). Plugging in the values, final velocity = 20 km/hr + (4 km/hr/s * 30 s) = 20 km/hr + 120 km/hr = 140 km/hr. So, the train's velocity after 30 seconds is 140 km/hr.
