A block of mass m is gently placed over a massive plank moving horizontal over a smooth surface with velocity `10 ms^(-1)`. The coefficient of friction between the block and the plank is 0.2. The distance travelled by the block till it slides on the plank is `[g = 10 ms^(-2)]`

A 2kg block is placed over a 4kg block and both are placed on a smooth horizontal surface. The coefficient of friction between the blocks is 0.20. The acceleration of the two blocks if a horizontal force of 12N is applied to the lower block is (g= 10 ms^(-2))

A bolck of mass m =2 kg is placed on a plank of mass M = 10 kg, which is placed on a smooth horizontal plane as shown in the figure. The coefficient of friction between the block and the plank is mu=(1)/(3) . If a horizontal force F is applied on the plank, then the maximum value of F for which the block and the plank move together is (g=10m//s^(2))
