A tennis ball is struck at the base line of the court, 14.5 m from the net. The ball is given an initial velocity with a horizontal component equal to 27.5 m/s at an initial elevation of 1.03 m. (a) What vertical component of initial velocity must be given to the ball, such that it barely clears the 1.00 m high net? (b) How far beyond the net will the ball hit the ground?

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 football quarterback is moving straight backward at a speed of 2.00 m/s when he throws a pass to a player 18.0 m straight downfield. (a) If the ball is thrown at an angle of 25° relative to the ground and is caught at the same height as it is released, what is its initial speed relative to the ground? (b) How long does it take to get to the receiver? (c) What is its maximum height above its point of release?

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 ?

A place-kicker must kick a football from a point 36.0 m (about 40 yards) from the goal. Half the crowd hopes the ball will clear the crossbar, which is 3.05 m high. When kicked, the ball leaves the ground with a speed of 21.4 m/s at an angle of 45.0° to the horizontal. (a) By how much does the ball clear or fall short (vertically) of clearing the crossbar? (Enter a negative answer if it falls short.) m(b) Does the ball approach the crossbar (and cross above or beneath it) while still rising or while falling? rising falling

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

A projectile is fired horizontally from a gun that is 53.0 m above flat ground, emerging from the gun with a speed of 220 m/s. (a) How long does the projectile remain in the air? (b) At what horizontal distance from the firing point does it strike the ground? (c) What is the magnitude of the vertical component of its velocity as it strikes the ground?
