Before jumping from the bridge, Martin throws his water bottle to a friend standing on the bank of the lake. The bridge is 7.0 m high. The friend is standing on the bank 15.0 m from the base of the bridge with their hand 1.0m above the ground. What speed must Martin throw the bottle horizontally for it to reach his friend's hand?

A rocket is fired at a speed of 75.0 m/s from ground level, at an angle of 61.5° above the horizontal. The rocket is fired toward an 11.0 m high wall, which is located 21.0 m away. By how much does the rocket clear the top of the wall?

A father demonstrates projectile motion to his children by placing a pea on his fork's handle and rapidly depressing the curved tines, launching the pea to heights above the dining room table. Suppose the pea is launched at 7.47 m/s at an angle of 83.0° above the table. With what speed (in m/s) does the pea strike the ceiling 1.90 m above the table?

A projectile is launched from point A with speed vo = 37 m/s. Determine the value of the launch angle a which maximizes the range R indicated in the figure. Determine the corresponding value R. Vo = 37 m/s Answers: a = α R= 92 m i 42.7 151.43 12.9 m -R m B

An archer shoots an arrow at a 87.61 m distant target; the bull's-eye of the target is at same height as the release height of the arrow. At what angle (in degrees) must the arrow be released to hit the bull's-eye if its initial speed is 30.41 m/s?

A guy is standing on a relatively flat surface (h = 0 m). A pesky drone is flying overhead at a height of 120 m above the ground and with a velocity of 15 m/s. The guy gets annoyed and fires an arrow with an initial velocity of 100 m/s the instant the horizontal distance between him and the drone is 5 m. At what angle must he fire the arrow in order to hit the drone? Take the guy's height to be 1.8 m. Just to clarify, would shooting an arrow follow the same rules as a regular projectile motion problem? Thanks.

A projectile is launched with an initial velocity of 24.0 m/s at an angle of 30.0° elevation. What are the components of the velocity of the projectile after 2.00 s?

The citizens of Paris were terrified during World War I when they were suddenly bombarded with shells fired from a long-range gun known as Big Bertha. The barrel of the gun was 36.6 m long, and it had a muzzle speed of 2.20 km/s. When the gun’s angle of elevation was set to 55.0°, what would be the range? For the purposes of solving this problem, ignore air resistance. (The actual range at this elevation was 121 km; air resistance cannot be ignored for the high muzzle speed of the shells.) km

A projectile is shot in the air from ground level with an initial velocity of 490 m/sec at an angle of 60° with the horizontal. (a)At what time (in seconds) is the maximum range of the projectile attained? (b)What is the maximum range (in meters)?
