A.) Your mass is 75.2 kg, and the sled s mass is 18.3 kg. The sled is moving by itself on the ice at 4.15 m/s. You parachute vertically down onto the sled, and land gently. What is the sled s velocity with you now on it?

B.) A block of mass 1.12 kg is placed on a frictionless floor and initially pushed northward, whereupon it begins sliding with a constant speed of 4.23 m/s. It eventually collides with a second, stationary block, of mass 3.60 kg, head-on, and rebounds back to the south. The collision is 100% elastic. What will be the speeds of the 1.12-kg and 3.60-kg blocks, respectively, after this collision?

PLEASE ANSWER ALL PARTS AND SHOW ALL WORK! In this section, all collisions will be completely elastic – that is, the total kinetic energy of the system will be constant throughout. Also, the collisions are entirely one-dimensional, with all motion taking place in either the northward or southward direction. The setting: a room with a frictionless floor. A block of mass 1 kg is placed on the floor and initially pushed northward, whereupon it begins sliding with a constant speed...

A block of mass m1 = 1.20 kg moving at v1 = 1.20 m/s undergoes a completely inelastic collision with a stationary block of mass m2 = 0.500 kg . The blocks then move, stuck together, at speed v2. After a short time, the two-block system collides inelastically with a third block, of mass m3 = 2.60 kg , which is initially at rest. The three blocks then move, stuck together, with speed v3. Assume that the blocks slide without...

Block 1 of mass 2.0 kg is sliding to the right with velocity 8.5 and collides with blocks 2 mass 1.5 kg moving with velocity -2. The collision is perfectly elastic. What is the velocity of block 1 after the collision? Positive velocity indicates motion to the right while negative velocity indicates motion to the left.
