please solve All the questions FULLY! thanks hero

K: knowing the correct method I: analyzing to use the correct method A: applying the process and calculation C: process following logical steps Each question (K:2, 1:2, A:2, C:2) Question 1: Object A with mass of 5.00 kg and a velocity of 8.00 m/s collides with an object B with a mass of 4.00 kg and a velocity of 3.00 m/s. After the collision the two objects travels together with one velocity. A. Determine the final velocity of the combined object. B. Determine the lost of kinetic energy during the collision. Question 2: A block B with mass me travels to the left with a velocity of v1 collides with a block A with mass mA. If the spring constant is k, determine an expression for the deformation. BQuestion 3: Block A has a mass of 2.50 kg travels at the speed of 5.00 m/s makes a head on collection with block B that has a mass of 1.50 kg at a speed of 7.50 m/s. Assume the collision is completely elastic, A. determine the velocities of block A and B after collision. B. determine the impulse of block A after collided with block B C. determine the forces of A acting on B if the contact time is 1.50 ms. Question 4: A plate with mass 550 g broke into three pieces. The piece with mass of 250 g moves to the north with a velocity of 46.0 m/s, a piece with mass 100 g moves to the [S45.E] with a velocity of 38.0 m/s. Determine the velocity of the third piece
