3. Imagine you pulled the block up to a height of 0.2 m along a 1° incline. How much work would you do in this process? How would the force required in this case compare to the values that you obtained in this lab? (1º is less of an angle than any of the trials)

Solve the following problems. Show computations and box the final answer. 1. A force of 3N acts through a distance of 12 m (parallel to the force). Find the work done. 2. A block of mass 10 kg is pulled 5 m upward in 1.5 seconds. Compute the work done. 3. Find the work done by a 2.0 kg load moved at a distance of 1 m horizontally.

1. 2. Draw a picture to represent this problem and show all work. A rope is being used to pull a rather large Christmas tree from your car to your house. The rope exerts a force of 83 pounds on the tree, and it makes an angle of 28° with the ground. Find the work done in moving the Christmas tree the 122 straight- line feet to your house. Round to the nearest unit and write your answer on the line provided. 1. Draw a picture to represent the problem. Show all work. You are left without a car after a party, and you must pull one of your "tipsy" friends home to your dorm room in a wagon that a friend let you borrow for the trip. A force of 117 pounds is made on the handle pulling the wagon up a hill that has an incline of 3.4° just in front of the dorm. Find the work done in moving the wagon the final 19 feet up the hill if the handle makes a 32° angle to a horizontal with the ground. Round to the nearest unit and write your answer on the line provided. 2.

Answer the following problem with the complete step-by-step process (showing the given, required, process/solution, and graph if possible). 1. The record number of boat lifts, including the boat and its ten crew members, was achieved by Sami Heinonen and Juha Räsänen of Sweden in 2000. They lifted a total mass of 653.2 kg approximately 4 in. off the ground a total of 24 times. Estimate the total work done by the two men on the boat in this record lift, ignoring the negative work done by the men when they lowered the boat back to the ground.

Suppose that 2 J of work is needed to stretch a spring from its natural length of 24 cm to a length of 41 cm. a. How much work (in J) is needed to stretch the spring from 29 cm to 37 cm? (Round your answer to two decimal places.) b. How far beyond its natural length (in cm) will a force of 35 N keep the spring stretched? (Round your answer one decimal place.)
