The archerfish uses a remarkable method for catching insects sitting on branches or leaves above the waterline. The fish rises to the surface and then shoots out a stream of water precisely aimed to knock the insect off its perch into the water, where the archerfish gobbles it up. Scientists have measured the speed of the water stream exiting the fish’s mouth to be 3.7 m/s. An archerfish spots an insect sitting 19 cm above the waterline and a horizontal distance of 30 cm away. The fish aims its stream at an angle of 39° from the waterline. Does the stream hit its mark?
A ball is tossed horizontally from the highest point of a 75 m building and lands 150 m from the base of the building. Ignore air resistance, and use a coordinate system whose origin is at the highest point of the building, with positive y upwards and positive x in the direction of the throw. What is the magnitude of the velocity of the ball just before it hits the ground, in meters per second?
An archer aims at a target that is a horizontal distance 55.0 m away and 5.0 m above the ground. The archer launches her arrow from of height of 1.5 m off the ground, and the arrow hits the target. The arrow is completely horizontal after sticking to the target (i.e., the arrow was traveling horizontally just before hitting the target). What was the initial speed of the arrow, in m/s?
A watermelon is thrown with a velocity of 5m/s in the +x direction off of a vertical ladder. The watermelon lands 3m from the base of the ladder. What is the height of the ladder?
A rock is thrown from the top of a building 94 m high, with a speed of 14 m/s at an angle 33 degrees above the horizontal. When it hits the ground, what is the magnitude of its velocity (i.e. its speed).
garden hose sprays a burst of water horizontally from 1.6 m above level ground. It hits a fence 2.1 m away, horizontally, at a height 0.93 m above the ground. What was the initial speed of the burst of water?
Ignoring air resistance, a helicopter is flying with a velocity of 90 m/s at an angle of 23 degrees above the horizontal. When the helicopter is 114 m directly above a dog that is standing on level ground, they dropped a crate. How far from the dog will the crate land?
A girl stands on a fishing pier and tosses a pebble into a pond. The pebble is thrown from a height of 2.50 m above the water surface with a velocity of 4.60 m/s at an angle of 60.0° above the horizontal. As the pebble strikes the water surface, it immediately slows down to exactly half the speed it had when it struck the water and maintains that speed while in the water. After the pebble enters the water, it moves in a straight line in the direction of the velocity it had when it struck the water. If the pond is 6.20 m deep, how much time elapses (in s) between when the pebble is thrown and when it strikes the bottom of the pond? 5.195 X
A soccer ball is kicked at a speed of 14.0 m/s at an angle of 36.0 degrees above the horizontal. The ball is in the air for 2.90 s.What is the maximum height the ball reaches?
An inflatable raft (unoccupied) floats down a river at an approximately constant speed of 3.9 m/s. A child on a bridge, 66 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?
A student standing on a cliff that is a vertical height d = 8.0 m above the level ground throws a stone with velocity v0 = 17 m/s at an angle θ = 27 ° below horizontal. The stone moves without air resistance; use a Cartesian coordinate system with the origin at the stone's initial position. With what speed, vf in meters per second, does the stone strike the ground?
A batter hits a fly ball with an initial velocity of 37 m/s at an angle of 32° from the horizontal. How much time does the outfielder have to get to the appropriate position to catch the ball?
