A bumper car was going 200kph. It took the bumper car 125 seconds to reach that speed What is the acceleration and momentum of that bumper car

Answer 1

To find the acceleration, we can use the formula:

acceleration = (final velocity - initial velocity) / time

Given:
Initial velocity (u) = 0 km/h (since the bumper car starts from rest)
Final velocity (v) = 200 km/h
Time (t) = 125 seconds

Converting the velocities to meters per second (m/s):
Initial velocity (u) = 0 km/h = 0 m/s
Final velocity (v) = 200 km/h = (200 * 1000) m/3600 s = 55.56 m/s

acceleration = (55.56 m/s - 0 m/s) / 125 s
acceleration ≈ 0.4445 m/s²

To find the momentum of the bumper car, we can multiply the mass (m) by its velocity (v). However, we need the mass of the car to calculate this momentum.
