Question

A car $C$ of mass $m_{1}$ rests on plank $P$ of mass $m_{2}$ . The plank rests on a smooth floor. The spring and pulley are ideal. The car starts and moves towards the pulley with acceleration

m_{1} > m_{2},

the string will remain under tension.

m_{1} = m_{2},

the string will have no tension, and

C

and

P

will have accelerations of equal magnitude.
