Hi, I need help with a super short hw and the questions are unrelated to each other so I'd appreciate any help and explanation :)

Part 2: Open-Ended Responses. All work and correct units MUST be shown for full credit. BOX in final answer. Use g =-10m/s*2 1. A student drops two eggs of equal mass simultaneously from the same height. Egg A lands on the tile floor and breaks. Egg B lands intact, without bouncing, on a foam pad lying on the floor. Compared to the magnitude of the impulse on egg A as it lands, the magnitude of the impulse on egg B as it lands is a) less b) can't be determined ) the same d) greater 2. A small beanbag that doesn't bounce and a bouncy rubber ball are dropped from the same height above the floor. They both have the same mass. Which one will impart the greater impulse to the floor when it hits? a) Beanbag b) Rubber ball ) Both the same d) Not enough info 3. A force of 6.0 Newtons changes the momentum of a moving object from 0 to 3.0 kg m/s. How long did the force act on the mass? 4. A 2.0-kg cart moving due east at 6.0 m/s collides with a 3.0-kg cart moving due west. The carts stick together and come to rest after the collision. What was the initial speed of the 3.0-kg cart? (3 pts) 5. A 0.86kg grenade is tossed on the ground with a velocity of 6 m/s West. If the grenade explodes into 2 pieces, one that has a mass of 0.32kg and travels East at 10 m/s. (A) What is the mass of the second piece (B) What is the velocity of the second piece? 6. A bowling ball of mass 4.0 kg, initially moving with a velocity of 2.0 m/s collides elastically with a steel ball of mass 6.0 kg. initially moving with a velocity of -4.0 m/s. What is the velocity of the bowling ball and steel ball after the collision? 7. A student who is 1.5m tall shoots a 0.03 kg dart out of a blow gun horizontally. The dart lands 7.3m away. A) How fast did the dart leave from the blow gun? B) If the dart took 0.21s to exit out of the blow gun while it was being shot out, with what average force did the boy blow into the gun? 8. A 79-kg fisherman in a 116-kg boat throws a package of mass m = 15 kg horizontally toward the right with a speed of v, =4.1 m/s as in the figure below. Neglecting water resistance, and assuming the boat is at rest before the package is thrown, find the velocity of the boat after the package is thrown. 9. A 0.750 kg golf ball, is thrown at a 0.050 kg billiard ball. The golf ball is moving at 22 m/s to the right. After the billiard ball is hit, it moves at 54.38 m/s to the right. With what velocity was the golf ball initially moving? 4. A 57-kg person is on top of a 2.1-kg skateboard and holds a 1.7-kg bowling ball. Initially the skateboard and the person are at rest. The person now throws the bowling bowl 18 m/s East. (A) Which direction will the skateboarder move? (B) With what velocity does the person recoil? 5. A 3.5-kg cannon on wheels is loaded with a 0.0527-kg ball. The cannon and ball are initially moving forward with a speed of 1.27 m/s. The cannon is ignited and launches a 0.0527-kg ball forward with a speed of 75 m/s. Determine the post-explosion velocity of the cannon
