A sphere of mass $m$ comes down on a smooth inclined plane from a point $B$ at a height of $h$ from rest. The magnitude of change in momentum of the particle between the position $A$ and $C$ (assuming the angle of inclination of the plane as $\theta $ with respect to the horizontal) is

A block of mass $0.18 \ kg$ is attached to a spring of force-constant $2 \ N / m$. The coefficient of friction between the block and the floor is $0.1$ . Initially the block is at rest and the spring is un-stretched. An impulse is given to the block as shown in the figure. The block slides a distance of $0.06 \ m$ and comes to rest for the first time. The initial velocity of the block in $m / s$ is $V = N / 10$. Then $N$ is

Given below are two statements:
Statement $I:$ A truck and a car moving with same kinetic energy are brought to rest by applying brakes which provide equal retarding forces. Both come to rest in equal distance.
Statement $II:$ A car moving towards east takes a turn and moves towards north, the speed remains unchanged. The acceleration of the car is zero.
In the light of given statements, choose the most appropriate answer from the options given below.
