A ball is tossed from an upper-story window of a building. The ball is given an initial velocity of 8m/s at 20° below the horizontal. It strikes the ground 3s later. (a) How far horizontally from the base of the building does the ball strike the ground? (b)Find the height from which the ball was thrown. (c) How long does it takes the ball to reach a point 10m below the level of launching?

A ball is tossed from an upper-story window of a building. the ball is given an initial velocity of 8.60 m/s at an angle of 16.0 degrees below the horizontal. it strikes the ground 6.00 s later. (a) how far horizontally from the base of the building does the ball strike the ground? (b) find the height from which the ball was thrown. (c) how long does it take the ball to reach a point 10.0 m below the level of launching?

A crow is flying overhead 10.0 m above the ground when it drops an acorn. When the acorn is dropped, it is moving at 10.0 m/s at an angle of 20.0° below the horizontal. Ignoring air resistance, how much time does it take the acorn to hit the ground? How far horizontally does the acorn travel before it hits the ground? Ignore air resistance.

A ball is thrown from a height h = 15 m above the ground. When the ball leaves with initial speed of 5.0 m/s at an angle of a= 34° below the horizontal. What is the magnitude of the dlisplacement between the launching point and where the ball hits the ground ?

An object is launched at a velocity of 20m/s in a direction making an angle of 25° upward with the horizontal. a) What is the maximum height reached by the object? b) What is the total flight time ( between launch and touching the ground) of the object? C) What is the horizontal range (maximum x above ground) of the object? d) What is the magnitude of the velocity of the object just before it hits the ground?

A toy cannon is located 15.0 m horizontally away from the base of a 10.5 m high building. A ball is fired from the cannon at an angle of 60.0°, and it passes some unknown distance above the top edge of the building, 1.5 s after it is being fired. (a) What should be the initial velocity of the ball so that it clears the building?(b) How far above the edge of the building is the ball when it passes over the top edge of the building?(c) Is the ball going down or still going up, at the point where it clears the wall?Justify your answer.(d) If the launch point is at the origin, what the x, y coordinates of the location at which the ball strikes the roof of the building?

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/sat an angle that is 25.0 degrees 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?

A ball is tossed from an upper-story window of a building. The ball is given an initial velocity of 8.10 m/s at an angle of 18.0° below the horizontal. It strikes the ground 5.00 s later. (a) How far horizontally from the base of the building does the ball strike the ground? m(b) Find the height from which the ball was thrown. m(c) How long does it take the ball to reach a point 10.0 m below the level of launching? 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, in m/s, 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.) v0 =

A ball is tossed from an upper-story window of a building. The ball is given an initial velocity of 8.40 m/s at an angle of 15.0° below the horizontal. It strikes the ground 5.00 s later. (a) How far horizontally from the base of the building does the ball strike the ground? (b) Find the height from which the ball was thrown. m (c) How long does it take the ball to reach a point 10.0 m below the level of launching?
