An object is projected horizontally at 8.0 m/s from the top of a 122.5 m cliff. How far from the base of the cliff will the object strike the ground?
An arrow is shot at 30.0° angle with the horizontal. It has a velocity of 49 m/s.
a) How high will it go?
b) What horizontal distance will the arrow travel?
3. A person kicks a rock off a cliff horizontally with a speed of 20 m/s. It takes 7.0 seconds to hit the ground, find:
a) height of the cliff
b) final vertical velocity
A ship fires its guns with a speed of 400 m/s at an angle of 35° with the horizontal. Find the range and maximum altitude.
A basketball is held over head at a height of 2.4 m. The ball is lobbed to a teammate at 8 m/s at an angle of 40°. If the ball is caught at the same height it was tossed at, how far away is the teammate?
Suppose the ball in #6 was missed, what would the range be?
An athlete executing a long jump leaves the ground at angle of 30.0° and travels 7.80 m.
a) What is the takeoff speed?
b) If the takeoff speed was increased by 5.0%, how much longer would the jump be?
A hunter aims directly at a target (on the same level) 140 m away. If the bullet leaves the gun at a speed of 280 m/s, by how much will the bullet miss the target?
A ball is thrown horizontally from the roof of a building 50 m tall and lands 45 m from the base. What was the ball’s initial speed?
A fire hose held near the ground shoots water at a speed of 7.5 m/s. At what angle should the nozzle point in order that the water land 2.0 m away? Why are there two different answers to this problem?
A bullet traveling 800 m/s horizontally hits a target 180 m away. How far does the bullet fall before it hits the target?
A student threw a ball horizontally out of a window 8.0 m above the ground. It was caught by another student who was 10.0 m away. What was the initial velocity of the ball?
A baseball was hit at 45 m/s at an angle of 45° above the horizontal.
a) How long did it remain in the air?
b) How far did it travel horizontally?
