A 65 kg skater is attempting to clear the loop of death, which has a radius of 5.0 meters. He krnows that the maximum velocity he can achieve is 15 m/s at the top of the loop. V 15 m/s a) Calculate his kinetic energy as he travels the top of the loop. Your answer b) Calculate his potential energy at the top of the loop. Your onswer c) What must be the minimum height he needs to drop from in order to clear the loop at 15 ms?

A roller coster has a loop with 7.62 diameter. a) What is the minimum height above the bottom of the loop required to acheive enough speed so that the coaster does not loose contact with the track? b) How many g's does the passenger expirience at the top of the loop AND at the bottom of the loop upon entering the loop.? c) suppose the coaster came to rest at 3/4 h on the other side of the loop. What fraction of the energy was lost?

A 500N girl is in a tire swing that is attached to a rope 3m long and loops-the-loop. Determine the gravitational potential energy of the girl when the ropes are horizontal.

A roller coaster ride starts at a height of 35 m above the ground. The mass of the car is 450 kg. Assuming friction can be ignored. What will the speed of the car be at the top off the first 20 m loop?

a spring has a spring constant k of 140n/m. a 150 g block is placed against the spring and compressed 16 cm. a0 when the block is released how high up the slope does it rise? b) what is the kinetic energy at the highest point? c) what is the potential energy at the highest point.

Hi there!! My question is bolded below :) It is a multiple choice question, so I have also listed every possible answer.    A person with a mass of 42kg starts from rest at position A, as shown, and then slides down to positions B, C, and D. Calculate the gravitational potential energy of the person at A.   412 J   672 J   4.2 kJ   6.6 kJ Thanks!

A 8.67 kg8.67 kg particle is subjected to only conservative forces, and its potential energy diagram is shown.   Between points G and K, at what location is the particle moving the fastest? J G K The particle is moving at the same speed at all of the points listed here. I H At point D, the particle has a speed of 14.1 m/s.14.1 m/s. What is the maximum speed ?maxvmax achieved by the particle between points G and K? Assume the points on the graph can be determined to three significant digits. Therefore, the calculated value for maximum speed should contain three significant digits.

9. Consider a 59kg volleyball player who is jumping to spike the ball. Her 0 position is the bottom of the squat. At take-off, she has 320 J of kinetic energy and 580 J of potential energy. a. How high is her COM at takeoff? b. How fast is she going when she takes off? c. What will the height of her COM be at the highest point of the jump?
