You fire a ball with an initial speed of v at an angle o above the surface of an incline, which is itself inclined at an angle e above the horizontal. a) Find the distance, measured along the incline, from the launch point to the point when the ball strikes the incline. b) What angle o gives the maximum range, measured along the incline? Ignore air resistance.
7. A cliff with an angled summit 900 m above the valley floor is a popular jumping off point for base jumpers. One particular base jumper gets a running start and runs off the side of the cliff with a velocity of 4.00 m/s at an angle that is 25.0° below the horizontal, as shown. (a) How long is the base jumper in the air before she opens her parachute 150 m above the valley floor? (b) How far (horizontally) is she away from the cliff? Vo

You are attacking your enemy’s castle and prepare your catapult to launch a large stone at the castle wall. Asyour clan’s engineer, it is up to you to calculate the correct distance from the wall to fire your catapult. Youknow that the projectile will be launched from the catapult 8.2 m above the ground at a velocity of 40 m/s atan angle of 46◦ above the horizontal, and you want to hit the castle wall 3.0 m above the ground, where theprojectile will do the most damage. How far from the wall should your catapult be positioned?

A criminal is escaping across a rooftop and runs off the roof horizontally at a speed of 5.1m/s, hoping to land on the roof of an adjacent building. Air resistance is negligible. The e horizontal distance between the two buildings is D, and the roof of the adjacent building is 2.0m below the jumping-off point. Find the maximum value for D.
Acertain airplane has a speed of 297.6 km/h and is diving at an angle of 0 = 33.0° below the horizontal when the pilot releases a radar decoy (see the figure). The horizontal distance between the release point and the point where the decoy strikes the ground is d = 651 m. (a) How long is the decoy in the air? (b) How high was the release point?
An arrow was shot from a height of 1.6 5M toward a cliff of height H. it is shot with the velocity of 35 m/s at an angle of 60 degrees above the horizontal. It lands on the top edge of the cliff 3.6 s later. (A) what is the height H of the cliff in M? (B) what is the maximum height reached by the arrow along as trajectory in meters? (C) what is the arrow speed just before hitting a cliff in m/s?
In 2007, Michael Carter (U.S.) set a world record in the shot put with a throw of 24.77 m. What was the initial speed of the shot if he released it at a height of 2.10 m and threw it at an angle of 38.0° above the horizontal? (Although the maximum distance for a projectile on level ground is achieved at 45° when air resistance is neglected, the actual angle to achieve maximum range is smaller; thus, 38° will give a longer range than 45° in the shot put.)
