Find the velocity of blocks after the collision

Reference no: EM13263592

1. a 3.0 kg block slides along a frictionless horizontal surface with a soeed of 7 m/s. after sliding a distance of 2 m the block makes a smooth transition to a frictionless ramp inclined at an angle of 40 to the horizontal :

a- what distance along the ramp does the block slide before coming momentarily to rest ?

b- describe the motion block(if any) after it momentarliy comes to rest ?

2. a 5 kg block moving at 4.0 m/s collides and sticks with a second stationary block of mass 3.0 kg

a- find the velocity of blocks after the collision

b- what percentage of the initial kinetic energy of the blocks is lost during this collision ?
