An ideal spring with a spring constant of 200 N/m is compressed 15 cm. A 300 g block is placed in front of the spring and the spring is released so that the block is launched to the right as shown. The initial height of the spring and block above the ground is 1.0 m. The height of the end of the ramp is 1.5 m above the ground. (Ignore friction)
a) At what speed does the block leave the spring?
b) How fast is the block moving when it first becomes airborne?
c) How fast is the block moving when it hits the ground?
d) What is the largest mass of the block that will still allow it to reach the ground? (Find where it just barely gets over the top of the ramp)
