On a warm spring day, the last icicle on the roof falls to the ground. The icicle has a mass of 0.4 kg, and starts at a rest and a height of 6.9 m above the ground.
A. What is the magnitude of the velocity of the icicle just before it hits the ground? Ignore air resistance.
m/s
B. Now, we will model the icicle hitting the ground as an object falling onto and then compressing a spring. (The small piece of ground that the icicle hits is the spring.) The icicle compresses the spring by 0.13 meters before coming to a (momentary) stop. What is the spring constant of the spring? Hint: both gravitational and spring potential energy changed in this problem.
N/m

A large building has an inclined roof. The length of the roof is 45.5 m and the angle of the roof is 20.0° below horizontal. A worker on the roof lets go of a hammer from the peak of the roof. Starting from rest, it slides down the entire length of the roof with a constant acceleration of 3.35 m/s2. After leaving the edge of the roof, it falls a vertical distance of 28.0 m before hitting the ground. (a)...

A large building has an inclined roof. The length of the roof is 45.5 m and the angle of the roof is 23.0° below horizontal. A worker on the roof lets go of a hammer from the peak of the roof. Starting from rest, it slides down the entire length of the roof with a constant acceleration of 3.83 m/s2. After leaving the edge of the roof, it falls a vertical distance of 30.5 m before hitting the ground. (a)...

Pablo is at the top of a roof with a pitch of 34.5 degrees. Aaron accidently drops a roll of duct tape (radius of 7.22 cm, mass of 0.335 kg) from the top of the roof. The tape rolls down the roof for 3-m before falling off. The tape then falls 3.88 m to the ground. Find the total time between the time the duct tape starts to roll and the time it hits the ground.

6. [10 points) For the following question, to model the free fall of a falling rock, assume the usual idealizing simplifications for solving "free fall" problems. Work with the approximate value g = 9.8 m/s2 for the Earth's gravitational acceleration. Consider the following experiment. The Leaning Tower of Pisa is known worldwide for its nearly four- degree lean. The height of the tower is 55.86 meters from the ground on the low side, and 56.67 meters on the high side....

1. A 125-kg load is lifted 12.0 m vertically with an acceleration a -0.32g by a single cable. Determine: (a) the tension in the cable, (b) the net work done on the load, (c) the work done by the cable on the load, (d) the work done by gravity on the load, and (e) the final speed of the load assuming it started from rest. 2.
