A 7.80-g bullet moving at 560 m/s penetrates a tree trunk to a depth of 4.80 cm. (a) Use work and energy considerations to find the average frictional force that stops the bullet. (b) Assuming the frictional force is constant, determine how much time elapses between the moment the bullet enters the tree and the moment it stops moving.
A toy gun uses a spring to project a 5.4-g soft rubber sphere horizontally. The spring constant is 8.0 N/m, the barrel of the gun is 17 cm long, and a constant frictional force of 0.034 N exists between barrel and projectile. With what speed does the projectile leave the barrel if the spring was compressed 6.1 cm for this launch? (Assume the projectile is in contact with the barrel for the full 17 cm.)

It is crazy hot outside, so you decide to make a water slide by running your garden hose over a tarp on a hill.. You find a hill that is 32 m high to slide down. After a couple trips. you want to go faster, so you rig up a bungee cord to give you a head start at the top of the hill, The bungee cord can be treated as a spring with a spring constant of 184 You have a mass of 77 kg and you compress your "spring" by a distance of 1.5 m before beginning your slide. Assume there is no friction at the top of the hill or on the hill Bungee/spring Grass-covered portion What is your speed at the top of the hill after you leave the spring m Vtop What is your speed after sliding to the bottom of the hill? Voottom m At the bottom of the hill, you reach a horizontal section where the tarp ends and you slide across the gress.

The elastic energy stored in your tendons can contribute up to 35% of your energy needs when running. Sports scientists find that (on average) the knee extensor tendons in sprinters stretch 42 mm while those of nonathletes stretch only 35 mm. The spring constant of the tendon is the same for both groups, 33 N/mm. What is the difference in maximum stored energy between the sprinters and the nonathletes?
