A football quarterback is moving straight backward at aspeed of 2.00 m/s when he throws a pass to a player 18.0 mstraight downfield. The ball is thrown at an angle of 25.0ºrelative to the ground and is caught at the same height as it isreleased. What is the initial velocity of the ball relative to thequarterback ?
A hockey puck glides across the ice at 32.5 m/s, when a player whacks itwith her hockey stick, giving it an acceleration at 64.3◦to its original direction. Theacceleration lasts 50.3 ms and the puck’s displacement during this time is 1.76 m. Findthe magnitude of the puck’s acceleration.
A rocket is fired at a speed of 83.0m/s from ground level, at an angle of 66.0degrees above the horizontal. The rocket is fired towards an 28.8m high wall, which is located 25.0m away. The rocket attains its launch speed in a neglibly short period of time, after which its engines shut down and the rocket coasts. By how much time does the rocket clear the top of the wall?
A student ires a canonball with a speed of 35.0m/s from a height of 50.om/s at an angle of 62 degrees. How long did the ball remain in the air ? How far from the base of the building did the ball land? How fast was the ball moving as it struck the ground?
A chinook salmon has a maximum underwater speed of 3.58 m/s, but it can jump out of water with a speed of 6.26 m/s. To move upstream past a waterfall, the salmon does not need to jump to the top of the fall, but only to a point in the fall where the water speed is less than 3.58 m/s; it can then swim up the fall for the remaining distance. Because the salmon must make forward progress in the water, let's assume it can swim to the top if the water speed is 3.00 m/s. (a) If water has a speed of 2.02 m/s as it passes over a ledge, how far below the ledge will the water be moving with a speed of 3.00 m/s? (Note that water undergoes projectile motion once it leaves the ledge. The water's velocity is initially horizontal as it passes over the ledge. Enter the magnitude of the distance only.) Your response differs from the correct answer by more than 10%. Double check your calculations. _______m (b) If the salmon is able to jump vertically upward from the base of the fall, what is the maximum…

An inquisitive physics student and mountain climber climbs a 51.0-m-high cliff that overhangs a calm pool of water. He throws two stones vertically downward, 1.00 s apart, and observes that they cause a single splash. The first stone has an initial speed of 2.06 m/s. (b) What initial velocity must the second stone have if the two stones are to hit the water simultaneously?
A clown juggle balls while doing other activities. In one act, she throws a ball vertically upward, and while it is in the air, she runs to and from a table 5.5 m away at constant speed of 2.5 m/s, returning just in time to catch the falling ball. With what minimum initial speed must she throw the ball upward to accomplish the act?

You can use any coordinate system you like to solve aprojectile motion problem. To demonstrate the truth of this statement, consider a ball thrown off the top of a building witha velocity vS at an angle u with respect to the horizontal. Letthe building be 50.0 m tall, the initial horizontal velocity be9.00 m/s, and the initial vertical velocity be 12.0 m/s. Chooseyour coordinates such that the positive y - axis is upward, thex - axis is to the right, and the origin is at the point where theball is released. (a) With these choices, find the ball’s maximumheight above the ground and the time it takes to reachthe maximum height. (b) Repeat your calculations choosingthe origin at the base of the building.
