Can someone help with these couple questions?
1. Two friends, Bunny (5kg) and Rabbit (8kg) are on skates on anice rink. They are facing each other and stationary at first. The,Bunny gives Rabbit a push which last for 0.1s. The push causesRabbit to move at 3 m/s after the push ends.
a. What is the force (magnitude and direction) that Rabbitexperiences from Bunny's push?
b. What is Bunny's acceleration during the push?
2. A canon at the top of a 200-m-tall cliff launches babybunnies at an angle of 30 degrees below the horizontal. A net isplaced m horizontally from the base of the cliff. Use projectilemotion method to determine
a. The speed with which the bunnies must be launches in orderthat they land in the net.
b. The time needed for the entire flight.
3. Bunnies are participating in an extreme sport, where they aredropped from a plane 150m above the ground. For 3.0 seconds, thebunnies are in free fall. Then, their parachutes open, and theyfall with a constant velocity until they hit the ground.
a. How fast are the bunnies moving at the moment just beforethey hit the ground?
b. Find the total time of travel from the plane to theground.
4. Zebra is twice as heavy as his friend Gazelle. If Zebra isrunning at half the speed of Gazelle, how much greater is hiskinetic energy compared to Gazelle's? (Hint: Find a ratio of thetwo friends' kinetic energies).
