3. 15. A skateboarder shoots off a ramp with a velocity of 6.6 m/s, directed at an angle of 58° above the horizontal. The end of the ramp is 1.2 m above the ground. Let the x axis be parallel to the ground, the +y direction be vertically upward, and take as the origin the point on the ground directly below the top of the ramp. (a) How high above the ground is the highest point that the skateboarder reaches? (b) When the skateboarder reaches the highest point, how far is this point horizontally from the end of the ramp?
Because of your physics background, you have been hired as a consultant for a newmovie about Galileo. In one scene, he climbs up to the top of a tower and, in frustration over the people who ridicule his theories, throws a rock at a group of them standing on the ground. The rock leaves his hand at 30 degrees from the horizontal. The script calls forthe rock to land 15 m from the base of the tower near a group of his detractors. It isimportant for the script that the rock takes precisely 3.0 seconds to hit the ground sothat there is time for a good expressive close-up. The set coordinator is concerned thatthe rock will hit the ground with too much speed, causing cement chips from the plazato injure on of the high priced actors. You are told to calculate that speed.
Solve the following Problem using the Horizontal Projection Equation. An archer shoots an arrow horizontally at a target 15 m away. The arrow is aimed directly at the center of the target but it hits 25 cm lower. What is the initial velocity of the arrow? A firefighter jumps out of the window into a net. If the window is 25 m above the net, (a.) At what speed does the firefighter hit the net? (b.) How long will it take the firefighter to hit the net? A little girl throws her jackstone ball horizontally out of the window with a velocity of 30 m/s. If the window is 3 m above the ground. How far will the ball travel before it hits the ground?
