William Tell is said to have shot an apple off his son’s head with an arrow. If the arrow was shot with an initial speed of 59.0 m/s and the boy was 25.0 m away, at what launch angle above the horizontal did Bill aim the arrow? (Assume that the arrow and apple are initially at the same height above the ground. Hint: sin2θ = 2sinθcosθ)

An arrow is shot at an angle of ?=45? above the horizontal. The arrow hits a tree a horizontal distance D=220m away, at the same height above the ground as it was shot. Use g=9.8m/s2 for the magnitude of the acceleration due to gravity. Suppose someone drops an apple from a vertical distance of 6.0 meters, directly above the point where the arrow hits the tree. How long after the arrow was shot should the apple be dropped, in order...

an arrow is shot from the top of a 475m tall building with an initial velocity of 46m/2 at an angle of 38 degrees above the horizontal. A nearby building is located 295 meters away. a) What are the horizontal and vertical components of the arrow's velocity when it reaches the nearby building? b) what are the magnitude and direction of the velocity of the arrow when it reaches the nearby building? c) what is the maximum height above the...

You are watching an archery tournament when you start wondering how fast an arrow is shot from the bow. Remembering your physics, you ask one of the archers to shoot an arrow parallel to the ground. You find the arrow stuck in the ground 65.0 m away, making a 2.8 ∘ angle with the ground. Ignore all possible aerodynamic effects on the motion of the arrow. Use 9.80 m/s2 for the acceleration due to gravity. a-For how much time was...

In the Hunger Games, Katniss shoots an arrow at an apple in a pig’s mouth using a longbow. After careful analysis of the scene, my daughter and I estimate she is standing 12 m away and 3.5 m below her target. A typical shot from a longbow reaches speeds of 55 m/s. a) At what angle above the horizontal must she fire the arrow? There are two solutions (what do they correspond to?) and which one would be the one...

1. In the 1970 National Basketball Association championship, Jerry West made a 60 ft shot from beyond half court to lead the Los Angeles Lakers to an improbable tie at the buzzer with the New York Knicks. Suppose West threw the ball at an angle of 45.0∘above the horizontal. The basket is 10 ft from the court floor. Neglecting air resistance, estimate the initial speed of the ball. (The Knicks won the game in overtime.) 2. Robin would like to...
