Q1.) A 0.290 kg block on a vertical spring with a spring constant of 5.00 ? 103 N/m is pushed downward, compressing the spring 0.110 m. When released, the block leaves the spring and travels upward vertically. How high does it rise above the point of release (include units)?

What would the velocity of the block be when it was 0.5 m above the point of release (include units)?

Q 2.) A child and sled with a combined mass of 60.0 kg slide down a frictionless hill. If the sled starts from rest and has a speed of 13.0 m/s at the bottom, what is the height of the hill (include units)?

Q 3.) A 45.0 kg pole vaulter running at 10.0 m/s vaults over the bar. Assuming that the vaulter's horizontal component of velocity over the bar is 1.0 m/s and disregarding air resistance, how high was the jump (include units)?

Q 4.) A 50 kg person rolls on a 2 kg skateboard with a velocity of 15 m/s. The skateboarder runs into a large rubber band with a spring constant of 80 N/m. How far will the cord stretch till the skateboarder stops moving forward (include units)?
