Question
A particle of mass m moving horizontally with v0 strikes a smooth wedge of mass M, as shown in figure. After collision, the ball starts moving up the inclined face of the wedge and rises to a height h. When the particle has risen to a height h on the wedge, then choose the correct alternative(s)
- The particle is stationary with respect to ground
- Both are stationary with respect to the centre of mass
- The kinetic energy of the centre of mass remains constant
- The kinetic energy with respect to centre of mass is converted into potential energy
The correct answer is: Both are stationary with respect to the centre of mass
