A particle of mass `m` moving with a velocity `(3hati+2hatj)ms^-1` collides with another body of mass M and finally moves with velocity `(-2hati+hatj)ms^-1`. Then during the collision

A body of mass 3 kg moving with a velocity (2hati+3hatj+3hatk) m/s collides with another body of mass 4 kg moving with a velocity (3hati+2hatj-3hatk) m/s. The two bodies stick together after collision. The velocity of the composite body is

A body of mass 3 kg moving with a velocity (2hati+3hatj+3hatk) m/s collides with another body of mass 4 kg moving with a velocity (3hati+2hatj-3hatk) m/s. The two bodies stick together after collision. The velocity of the composite body is

A body of mass 3 kg moving with a velocity (2hati+3hatj+3hatk) m/s collides with another body of mass 4 kg moving with a velocity (3hati+2hatj-3hatk) m/s. The two bodies stick together after collision. The velocity of the composite body is

A body of mass 100 gm moving with an initial velocity of 4ms^(-1) collides with another body of mass 150 gm moving in opposite direction with velocity 6 ms^(-1) . If the collision is perfectly inelastic, then after the collision,

A body of mass m moving with a velocity v in the x direction collides with another body of mass M moving in y direction with a velocity V . They coalesce into one body during collision.

A particle moving with velocity (2hati-3hatj) m/s collides with a surface at rest in xz–plane as shown in figure and moves with velocity (2hati+2hatj) m/s after collision. Then coefficient of restitution is :
