Question

A child (32 kg) jumps up and down on a trampoline. The trampoline exerts a spring restoring
force on the child with a constant of 5000 N/m. At the highest point of the bounce, the child
is 1.0 m above the level surface of the trampoline. What is the compression distance of the
trampoline? Neglect the bending of the legs or any transfer of energy of the child into the
trampoline while jumping.

A toy gun uses a spring to project a 6.2-g soft rubber sphere horizontally. The spring constant is 8.0 N/m, the barrel of the gun is 12 cm long, and a constant frictional force of 0.039 N exists between barrel and projectile. With what speed does the projectile leave the barrel if the spring was compressed 5.7 cm for this launch? (Assume the projectile is in contact with the barrel for the full 12 cm.)

A spring with constant k=200 N/m is fixed to the top of an incline that makes an angle of 40.0 degrees with the horizontal. A projectile with mass 1.10 kg is projected up the plane, form an initial horizontal position that is d from the end of the uncompessed spring. a) If the incline is frictionless and the initial kinetic energy of the projectile is 17.0 J, how much will the spring be compressed? b) If there is a coefficient of friction of 0.200 and the spring must compress by 1.50 cm at the moment when the projectile stops (say, to trigger an event like a switch) then what must the initial speed of the projectile be? All other conditions are same as in the setup.
MWN H. 2 m 0.5 m, 4=0.3 As shown in the picture, a block of mass m = 2.3 kg compresses a spring by x - 0.4 m (spring %3D constant k = 362 N/m). The block is let go from rest, then shoots away from the spring and slides %3D down a frictionless incline a vertical drop of 2.0 m. It then slides across a rough horizontal patch of length 0.5 m (coefficient of kinetic friction 0.3), then up a frictionless incline. What is the correct equation to solve for the maximum vertical height H in meters the block reaches?
