(1) If a ball was thrown horizontally off a 155 meter cliff with a velocity of 13.5 m/s; (a) How much time would the ball spend in the air? (b) How far from the base of the cliff would the ball land? (c) At what angle would the ball hit the ground (HINT: look at horizontal and vertical velocities)

A ball is thrown horizontally from the top of a 61.5-m building and lands 113.8 m from the base of the building. Ignore air resistance. (Assume the ball is thrown in the +x direction and upward to be in the +y direction.) (a) How long is the ball in the air? (b) What must have been the initial horizontal component of the velocity? (Indicate the direction with the sign of your answer.) m/s (c) What is the vertical component of the velocity just before the ball hits the ground? (Indicate the direction with the sign of your answer.) m/s (d) What is the velocity (including both the horizontal and vertical components) of the ball just before it hits the ground? magnitude m/s direction ° counterclockwise from the +x-axis

Question 4. cargo plane flying level at an altitude of h and with speed vo camping supplies, targeting a campsite 1000 meters away from the point below the plane when the crate fell. = 100 m/s drops a wooden crate full of (a) How long is the crate in the air? (b) What value of h will get the crate to the campsite? (c) If h were 1000 meters, where would the crate land?

A ball is kicked with an initial velocity of 11 m/s in the horizontal direction and 14 m/s in the vertical direction. (a) At what speed (in m/s) does the ball hit the ground?

A cannon is placed at the bottom of a cliff61.5 m high. If the cannon is fired straight upward, the cannonballjust reaches the top of the cliff. (a) What is the initial speed of thecannonball? (b) Suppose a second cannon is placed at the top ofthe cliff. This cannon is fired horizontally, giving its cannonballsthe same initial speed found in part (a). Show that the range of thiscannon is the same as the maximum range of the cannon at thebase of the cliff. (Assume the ground at the base of the cliff is level,though the result is valid even if the ground is not level.)

(2) If two people were standing 30 meters apart and one person threw the ball to the other with a horizontal velocity of 21.5 m/s at a height of 2.0 meters: (a) How much time would the ball spend in the air? (b) Would the ball reach the other person or fall short? (c) If it falls short, by how much did it fall short? If it reaches, how far above the ground would the ball hit the other person?
