A bungee cord is rated at 545N/m. The jump is off a bridge above a river. Unstretched, the bungee cord is 68.0 m long. A 72.0 kg person jumps. They fall till and the cord begins to stretch. Find the amount by which cord has stretched when the person’s speed is 14.0 m/s.
For its size, the commonflea is one of the most accomplished jumpers in the animal world.A 2.0-mm-long, 0.50 mg flea can reach a height of 20 cm in a singleleap. If a 65 kg, 2.0-m-tall human could jump to the same height compared with his length as the flea jumps compared with its length, how high could the human jump, and what takeoff speed would the man need?
A 7.80 g bullet is initially moving at 650 m/s just before it penetrates a tree trunk to a depth of 4.70 cm. (a) What is the magnitude of the average frictional force (in N) that is exerted on the bullet while it is moving through the tree trunk? Use work and energy considerations to obtain your answer. b) Assuming the frictional force is constant, how much time (in s) elapses between the moment the bullet enters the tree trunk and the moment it stops moving?
2. Tarzan, whose weight is W = 688 N, swings from a vine of length L = 18 m. He starts his swing from rest at the edge of a cliff that is h = 3.2 m above the bottom of his trajectory. The vine will break if its tension exceeds T 900 N. W (a) Does the vine break? If the vine does not break, what is the greatest (b) tension in the vine? If the vine breaks, at what angle with respect to the vertical will it break?
A high jumper, falling at 4.0 m/s, lands on a foam pit and comes to rest, compressing the pit 0.40 m. If thepit is able to exert an average force of 1200 N on the high jumper in breaking the fall, what is the jumper'smass? (60 kg)
Jake bungee jumps from a hot air balloon 55 m above the ground. She knows that 5.0 m of bungee cord will stretch by 1.5 m with her weight. What length of rope should she use to just miss the ground?
Ed, Edd and Eddy love to play on a seesaw. It consists of a 1-kg board with a length of 8 meters. One day, the other end broke down. They had to cut it by a meter and maintain the pin support in its original position. Then, they tried the seesaw altogether. Ed (m = 55kg) sat on one side about 3m from the pin while Edd (m = 40kg) and Eddy (m = 40kg) on the other side. If Edd was about 3m as well from the pin, calculate the following: The manitude of the reaction force (N) exerted by the pin support on the board. Assume Eddy is in between Ed and Edd. (mass of board = 1kg)
a. Calculate the force (in N) needed to bring a 950 kg car to rest from a speed of 80.0 km/h in a distance of 110 m (a fairly typical distance for a non-panic stop). b. Suppose instead the car hits a concrete abutment at full speed and is brought to a stop in 2.00 m. Calculate the force exerted on the car and compare it with the force found in part (a). force in (b)/force in (a)=

Tarzan grabs a vine of length L=8.9 m and attempts to swing across the crocodile infested river. The vine breaks just as Tarzan is at lowest point of his swing, a horizontal distance D=60 m and H= 4.5 m above the riverbank. You barely mix it across, landing on the edge of the riverbank. The tension in the vine when it broke was a 1000 N. Find Tarzan's mass.
Calculate the force needed to bring a 900 kg car to rest from a speed of 90.0 km/h in a distance of 110 m (a fairly typical distance for a nonpanic stop).N(b) Suppose instead the car hits a concrete abutment at full speed and is brought to a stop in 2.00 m. Calculate the force exerted on the car and compare it with the force found in part (a), i.e. find the ratio of the force in part(b) to the force in part(a).(force in part (b) / force in part (a))
