2. A box starts at rest at the top of a very smooth ramp. The top of the ramp is 1.50 m above the ground. At the bottom of the ramp, just after the ramp levels off, is a spring with a spring constant of 1500 N/m. The box compresses the spring 2.00 cm before it momentarily comes to rest. (a) What types of energy are present: at the top? at the bottom? when the spring is compressed? (b) What is the mass of the box? If the mass of box doubled, how far would the spring have been compressed? 2. A box starts at rest at the top of a very smooth ramp. The top of the ramp is 1.50 m above the ground.
