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?
