A 69.5 kg bungee jumper is standing on a tall platform (h0 = 53 m), as seen in the photo. The bungee cord has an untrained length of L0 = 10 m, and when stretched, behaves like an ideal spring with a spring constant of k = 64.0 N/m. The jumper falls from rest, and the only forces acting on him are his weight and, for the latter part of the descent, the elastic force of the bungee cord (Assume the cord is attached at the center of mass and the center of mass drops from rest from the height of the platform.) What is his maximum speed during the fall? _______ m/s How high above the water is he when he reaches this speed? _______ m How high above the water is he when he reaches the lowest point in the fall? _______ m

In class we learned about Kate, a bungee jumper with mass ? = 50.0 kg who jumps off a bridge ofheight ℎ = 25.0 m above a river. After she jumps, the bungee cord – which behaves as an ideal springwith spring constant ? = 28.5 N/m – stretches to a new equilibrium with length ?? = 20.0 m. a) What is the unstretched length of the bungee cord without Kate attached? After hanging out at this new equilibrium for a bit, Kate starts to get worried. She yells up to her friend Ken, who is frantically trying to figure out how to hoist her back up. After a couple of hours of this, Katestarts to get hungry. She begs Ken to throw her down a backpack full of provisions with mass ? = 15.0 kg. Ken complies, dropping the bag from the bridge with no initial velocity. Throughout this problem, youmay neglect all sources of friction or other non-conservative forces. b) Kate catches the bag when it gets to her. What are the momenta of Kate and the bag just before she catches it? What about just after?

Q 03: a 10kg mass is attached to a spring having the spring constant of 140N/m. The mass is started in motion from equilibrium position with an initial velocity of 1m/s in the upward direction and with an external force F (t) = 5 sin t FORM the model/governing ODE and the subsequent motion of the mass if the force due to air resistance is -90v N.
A scene in a movie has a stuntman falling through a floor onto a bed in the room below. The plan is to have the actor fall on his back, but a researcher has been hired to investigate the safety of this stunt. When the researcher examines the mattress, she sees that it effectively has a spring constant 65144 N/m for the area likely to be impacted by the stuntman, but it cannot depress more than 13.55 cm without injuring him. To approach this problem, consider a simplified version of the situation. A mass falls through a height of 3.32 m before landing on a spring of force constant 65144 N/m. Calculate the maximum mass that can fall on the mattress without exceeding the maximum compression distance.
