9. Your friends (apparently, they decided to join you after all) dares you to jump on the rare white rhino you are watching from the safety of your safari jeep. Figuring what could be the harm in jumping on a rhinò, you take a running start and jump on the rhino which takes off and accelerates to a speed of 14.2 m/s in 7.2s. Calculate the following:

Gayle runs at a speed of 4.00 m/s and dives on a sled, initially at rest on the top of a frictionless, snow-covered hill. After she has descended a vertical distance of 5.00 m. her brother, who is initially at rest, hops on her back, and they continue down the hill together. What is their speed at the bottom of the hill if the total vertical drop is 15.0 m? Gayle's mass is 50.0 kg, the sled has a mass of 5.00 kg, and her brother has a mass of 30.0 kg.
a 600 gram banana sliding north on a frictionless table at 2.5 meters per second bounces of a 400 gram kiwi fruit that is initially at rest , after colliding the banana continues moving north at 0.5 meters per second. At the North edge of the track is a frictionless inclined ramp which the kiwi fruit slides up to then the kiwi comes back down the ramp , without losing energy , and will now be moving south , the kiwi will catch up and hit the banana again. If the last collision took 20 milliseconds , what was the average force exerted by the banana on the kiwi during the collision (magnitude and direction ) ? by the kiwi on the banana?

1. It's 5:00 PM and Kurdapya needs to finish her physics module, one of the problems tates that a rocket and a spacecraft were attached and has a combined mass of 3.8 × 10⁵kg and is to reach a speed of 12.3 km/s, she needs to know how much kinetic energy will it have. 2. The next day, Kurdapya craved for some riped guava fruit. She has to climb the guava tree however she realized that she is already 65 kg and the tree is 7.2 meters high. Let us calculate the power required for her to climb the tree in 15 seconds.
1. After a tornado, a 0.55g straw was found embedded 2.3cm into the trunk of a tree. If the average force exerted o the straw by the tree was 65N, what was the speed of the straw when it hit the tree?Explain and draws.
An object of mass 8 kg has speed 30 m/s and is traveling in a direction that is 17 degrees W of N. It collides with an object of mass 9 kg, which has speed 44 m/s and is traveling in a direction that is 29 degrees S of E. The two have a completely inelastic collision. What is their final speed, in m/s? (Please answer to the fourth decimal place - i.e 14.3225)
Sue gets up on the roof to clean off the leaf litter. Upon trying to get back down the ladder, she gets scared and doesn't think she can go down that way. She contemplates jumping off the roof, but has heard that is unsafe. If the roof is 10 feet high and she has a mass of 68.1 kg, how fast would she be going when she hit the ground if she jumped? State your answer in mi/hr.
A 115kg rugby player is initially running at 5.5 m/s in the + direction, but collides with a goalpost and experiences a backward force of 1.71 × 10^4 N for 5.25 × 10^-2 s. what is the final \velocity of the rugby player in the horizontal direction
A rocket of mass 1.7x104 kg accelerates at 215 m/s2 for 21 s from an initial speed of 5031 m/s. How much kinetic energy (in J) has the rocket gained?
a 600 gram banana sliding north on a frictionless table at 2.5 meters per second bounces of a 400 gram kiwi fruit that is initially at rest , after colliding the banana continues moving north at 0.5 meters per second. How fast is the kiwi fruit going after the collision , and in which direction?
In 1896 in Waco,Texas,William Crush parked two locomotives at opposite ends of a 6.4-km-long track, fired them up, tied their throttles open, and then allowed them to crash head-on at full speed in front of 30,000 spectators. Hundreds of people were hurt by flying debris; several were killed. Assuming each locomotive weighed 1.2 * 106 N and its acceleration was a constant 0.26 m/s2, what was the total kinetic energy of the two locomotives just before the collision?
