How do you find initial velocity after a collision?
If two particles are involved in an elastic collision, the velocity of the first particle after collision can be expressed as: v1f=(m1−m2)(m2+m1)v1i+2⋅m2(m2+m1)v2i v 1 f = ( m 1 − m 2 ) ( m 2 + m 1 ) v 1 i + 2 ⋅ m 2 ( m 2 + m 1 ) v 2 i .
How do you calculate initial velocity?
How do you find initial velocity?
- Work out which of the displacement (S), final velocity (V), acceleration (A) and time (T) you have to solve for initial velocity (U).
- If you have V, A and T, use U = V – AT.
- If you have S, V and T, use U = 2(S/T) – V.
- If you have S, V and A, use U = SQRT(V2 – 2AS).
What is the acceleration of a car in m/s?
The answer is (60 mph – 0 mph) / 8s = (26.8224 m/s – 0 m/s) / 8s = 3.3528 m/s 2 (meters per second squared) average acceleration. That would be 27,000 miles per hour squared. That would be 27,000 miles per hour squared.
What is the initial velocity of a runner traveling 2 m/s?
A runner traveling with an initial velocity of 2 m/s accelerates at a constant rate of 1.1 m/s2 for a time of 3 seconds. What is his velocity at the end of this time? 5. A runner traveling with an initial velocity of 2 m/s accelerates at a constant rate of 1.1 m/s2 for a time of 3 seconds.
What is the acceleration of a truck traveling at 60 mph?
The answer is (60 mph – 0 mph) / 8s = (26.8224 m/s – 0 m/s) / 8s = 3.3528 m/s 2 (meters per second squared) average acceleration. That would be 27,000 miles per hour squared. Example 2: If a truck is travelling at 50 km/h and increases its velocity to 65 km per hour in 10 seconds, what is its acceleration?
Is there acceleration if the velocity is constant?
Velocity has both a magnitude (speed) and a direction. If the direction is changing there is an acceleration. B)No. If speed is constant there is no change so therefore no acceleration. C)No. Acceleration is the rate of change of velocity. If the speed is constant the velocity is not changing.
