An object of mass 50 kg is pulled with a force of 100 N on a smooth runway.
It acceleration is:
150 ms⁻².
500 ms⁻².
2 ms⁻².
0.5 ms⁻².
The figure shows an arrangement which is used to investigate collisions between two trolleys.
Trolley AB is initially stationary and the end of Y of the is closer to trolley A.
The runway is inclined to:
Cause acceleration of trolley A.
Give trolley A an initial velocity.
Reduce friction.
