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
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.
