Your nephew got a Nerf Bazooka gun for Christmas, so you take it outside to play with it (just like my uncles did when I was little). The bazooka is on your shoulder, 1.7 m above the ground. You aim the gun 30° above the horizontal and the big, foam projectile leaves the gun with an initial velocity of 31 You accidentally aim the bazooka at a tree that is a horizontal distance of 23 m away. How long does it take for the projectile to hit the tree? t = How high (above the ground) in the tree does the projectile get stuck? hfinal = Imagine you were more clever and aimed into an empty field with no obstructions. You can control how fast the projectile leaves the gun by pumping more times or fewer times (more pumps = faster projectile). What are TWO ways you could increase the amount of time that the projectile is in the air?

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 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?

Billy launches a tennis ball with a sling shot at an angle of 62 degrees above the horizontal at a speed of 45 meters per second . The tennis ball lands in a nearby tree. How far away is the tree?

A man is standing on a cliff which is 100 m above the lake. He throws a stone horizontally with a speed of 10m/s to the lake. What is the straight-line distance between the man and the stone when it hits the water?

An inflatable raft (unoccupied) floats down a river at an approximately constant speed of 5.2 m/s. A child on a bridge, 82 m above the river, sees the raft in the river below and attempts to drop a small stone onto the raft. The child releases the stone from rest. In order for the stone to hit the raft, what must be the horizontal distance between the raft and the bridge when the child releases the stone? m

Alice shoots a pebble horizontally with her slingshot from a window that is at a height H and it lands a distance D away from the building. She then shoots a pebble with the same initial velocity from a different window, but this time the pebble lands a distance D/2 away. How high is the window from which Alice takes the second shot? A. 4H B. 2H C. H D. H/2 E. H/4

How would I find the velocity of a basketball that is shot from 15 feet away and at a hoop 10 feet high? The person releases the ball from eight feet above the ground. What is the maximum height of the ball in the air?

A 2.00-m-tall basketball player is standing on the floor 10.0 m from the basket, as in the figure below. If he shoots the ball at a 40.0° angle with the horizontal, at what initial speed must he throw the basketball so that it goes through the hoop without striking the backboard? The height of the basket is 3.05 m. m/s 40.0 2,00 3.05 m 10.0 m

You are playing Hot Rod toy cars with your nephew and niece. Your nephew wanted to show off how fast he could launch a Hot Rod off the dining table 1.00 m above the floor by thrusting the car forward very fast but was no match against your niece who compensated slight lack of speed by pushing the car straight forward reaching a speed of 4.5 m/s at the edge of the table top when she let go of it. What was the magnitude of the final speed when it hit the floor?
