A 1.55-kg block is launched by a spring and slides along a ramp as shown. The spring has a spring constant of 1180 N/m and is compressed a distance, x, before being released. The block slides up a frictionless ramp of height, H=0.550 m, above where the block leaves the spring. At the top of the ramp it flies horizontally off the ramp. Just before leaving the ramp, the kinetic energy of the block is 8.54 J. After leaving the ramp, the block lands on a ledge a height, h=0.330 m, below where it leaves the ramp. Ignore air resistance. The figure is NOT drawn to scale.
What is the velocity of the block just as it leaves the return?

What is the distance, x, that the spring was compressed from equilibrium when launching the block?

How much time elapses between when the block leaves the ramp and it hits the ledge?

block 1 of mass m1 slides from rest along a frictionless ramp from an unknown height h and then collides with stationary block 2, which has mass m2 = 3m1 . The collision is an elastic one. After the collision, block 2 slides into a friction-filled region where the coefficient of kinetic friction is 0.5 and comes to a stop through a distance d = 10 m in that region. What is the height h?
