1. You are setting up for a pool party that has a 2.5 m high slide that launches
swimmers into the pool. To make it more exciting, you decide to string a steamer
across the pool so that the swimmers just clear it at their maximum height after
leaving the slide. The end of the slide is 0.75 m above the ground and is directed
20° above the horizontal. By watching people use the slide, you know the horizontal
distance to place the streamer, so you only need to determine the maximum height.
You are also curious how fast the swimmers are going when they enter the pool. In
your estimates, you can assume that the swimmer starts at rest at the top of the slide
and ignore friction on the slide and air resistance.
2.5 m
0.75 m
streamer
If the angle of the slide were different (say 15°) would either the maximum height or
the speed when entering the water be different?
Note: Use conservation of energy to answer these questions.
In a large printing operation, an employee using a clamp forklift truck that was transporting two waste-paper bales from the scrap paper area. One paper bale (∼0.5 ton) was placed on top of another 1 ton bale; however, the top bale was not strapped to the bottom bale. As the forklift driver made a turn, he had to brake suddenly for a nearby pedestrian. The sudden stop and turn caused the top bale to fall off and strike the pedestrian. A review of the accident showed that the forklift operator was trained and certified, but the employee was in an area where pedestrians were prohibited according to plant safety rules. Write at least three suggested preventive measures to avoid the recurrence of said case accident.
Provide three (3) preventive measures.
If the mass of the hanging-mass is increased and the mass of the cart remains the same, how would the steepness of the position versus t2 be affected?
The best-fit line would decrease in steepness.The best-fit line would increase in steepness. Impossible to determine because the net force is not a part of the position vs t2 graph.There would be no change in steepness.

Purpose: To understand the concept of work and power and to calculate the power generated by yourself or a friend. Materials: A tape measure, stairs, and a stopwatch, cell phone, or wristwatch. Key Physics Concept: Power is the rate of doing work. Power can be calculated by dividing the work done by the time it takes to do the work; in this case we will do work against gravity on a stair case (you may add your power in doing pushups to test your arm power). Can you guess what your peak horsepower is? You may do the stairs one at at time or multiple stairs at a a time; whatever is most safe and efficient for you.
