One object of mass 20 kg is moving with speed 10 m / s in west direction another object of mass 10 kg is moving with 15 m / s in North direction. Both collide and stick together. Choose the correct alternative.

Question

One object of mass 20 kg is moving with speed 10 m / s in west direction another object of mass 10 kg is moving with 15 m / s in North direction. Both collide and stick together. Choose the correct alternative., There K.E. is conserved as it is inelastic collision, There K.E. is conserved on it is elastic collision, There momentum is conserved as it is inelastic collision, There momentum is conserved as it is elastic collision

MARKS App · Accepted Answer

When object of mass 20 kg is moving with speed 10 m / s in west direction collide with object of mass 10 kg and stick together, hence it is perfectly inelastic collision. In inelastic collision, momentum is conserved only.
