Chapter 4, Problem 34P
A trebuchet was a hurling machine built to attack the walls of a castle under siege. A large stone could be hurled against a wall to break apart the wall. The machine was not placed near the wall because then arrows could reach it from the castle wall. Instead, it was positioned so that the stone hit the wall during the second half of its flight. Suppose a stone is launched with a speed of v0 = 28.0 m/s and at an angle of θ0 = 40.0°. What is the speed of the stone if it hits the wall (a) just as it reaches the top of its parabolic path and (b) when it has descended to half that height? (c) As a percentage, how much faster is it moving in part (b) than in part (a)?

A firework rocket is 85 m above the ground when it explodes. Immediately after the explosion one piece is moving 51 m/s at 23° to the upward vertical direction. A second piece is moving at 38 m/s at 11° below the horizontal direction. What what horizontal distance from the explosion site does each piece land?
Skeet Shooting is an Olympic sport for rifle marksmen. A skeet is a clay target. A lady marksman goes out to practice and sets her skeet launcher at a position 25 meters north and 40 meters west from where she intends to stand. When she yells “Pull!”, a skeet is launched due East at an angle of 37 degrees above the ground with an initial speed, vo. The marksman only fires due north. Two seconds after she yells “Pull!”, the bullet from her gun hits the clay skeet in the air. At what height did the clay skeet shatter? Neglect air friction effects. {Use sin(37o) = 3/5; cos(37o) = 4/5; and g = 10 m/s2 }

- Our pinoy pride, Kai Sotto, is now training for his upcoming 3x3 basketball tournament next year. Under International Basketball Federation (FIBA) rules, the three-point line is 6.75 meters from the center of the basket. If he will train for three-point shooting, what should be the ball's angle when he shoots the ball if he will try to shoot from a height as high as the basket with an initial velocity of 8.2 m/s? Is it 40°; 50°; 60°? How long would it take for the ball to reach the ring for each of the angles? What is the ball's maximum height for each of the angles? And how fast is the ball's horizontal and vertical initial velocities for each or the angles?arrow_forwardA group of collegiate golfers invent a game where they have to hit a golf ball up to the roof of a building that is about 23.76 m tall. The hole is 3.3 m away from the edge of the roof (label this in the figure). The roof is perfectly level all the way across. a) Isabella strikes the ball causing it to launch from the ground with an initial velocity of 22.70 m/s and at an angle of θ = 72.00 . Is it possible for Isabella to make her shot to the roof? Ignore wind resistance for part (a). b) Assuming that Isabella’s shot from part (a) made it to the roof and the shot is line up to go into the hole that is 3.30 m away from the edge of the roof. The golf ball has a mass of 45.93 g, and experiences a friction force of f=0.133 N. If the ball’s speed is larger than 5.90 m/s when at the hole it will be moving too fast and not go in. Will Isabella’s shot go into the hole?

She can do this by throwing her ball so that it lands directly on top of the pallino, which is x = 17 m horizontally downcourt from where she throws. If she releases the ball y = 0.90 m above the ground at an angle of 0 = 23° above the horizontal, then how much time will the ball spend airborne before hitting the pallino? Both balls may be treated as point particles in this problem.arrow_forwardA physics student stands on a cliff overlooking a lake and decides to throw a softball to her friends in the water below.
