A football quarterback is moving straight backwards at a speed of 2.9m/s when he throws a pass to a player 22 m straight downfield. The ball is thrown at an angle of 21 degrees relative to the ground and is caught at the same height as it is released. What is magnitude of the initial velocity of the ball relative to the quarterback in m/s? What angle above the horizontal does the initial velocity of the ball relative to the quarterback make? Give your answer in degrees.
a boy fires an arrow from a height of 1.80 m at an angle of 15° above the horizontal towards a target standing 15.00 m in front of him. He misses the target completely, and the arrow goes flying past the target and hits the ground 21.1 m behind the target. Determine the initial velocity of the arrow in m/s.

- In a basketball game, a player attempts to apply what he learned in physics under projectile motion. He realizes that from his position, he needs to exert 25 m/s for the ball to hit the ring before the end of the last quarter of the game. At what angle must he position the ball, for him get 3 points for his team to win the match.arrow_forwardA quarterback practices his throwing motion by throwing on the practice field, but misses the target. The ball is thrown with an initial speed of 13.24[m/s] at an angle of 35.0°. If the ball is released when it is 1.85[m] above the ground, determine the magnitude of the velocity of the ball the instant before it lands. Express your answer in m/s.arrow_forwardA soccer player decides that he can make this goal to win the game so he kicks the ball with a speed of 8.5 m/s at an angle of 25.0° above the horizontal. How long was the ball in the air, assuming that the ball lands on the same level it was kicked.arrow_forward
- A rocket is fired at a speed of 65.0 m/s from ground level, at an angle of 48.0° above the horizontal. The rocket is fired toward an 29.7-m high wall, which is located 39.0 m away. The rocket attains its launch speed in a negligibly short period of time, after which its engines shut down and the rocket coasts. By how much does the rocket clear the top of the wall?arrow_forwardOn a distant planet, golf is just as popular as it is on earth. A golfer tees off and drives the ball 2.30 times as far as he would have on earth, given the same initial velocities on both planets. The ball is launched at a speed of 48.4 m/s at an angle of 32.7 ° above the horizontal. When the ball lands, it is at the same level as the tee. On the distant planet, what are (a) the maximum height and (b) the range of the ball?arrow_forwardA soccer goal is 2.44 m high. A player kicks the ball at a distance 23 m from the goal at an angle of 26°, and the ball just hits the top of the goal. What is the initial speed of the soccer ball (in m/s)?arrow_forward
- A group of collegiate golfers invent a game where they have to hit a golf ball up to the roof of a building that is about 23.76 m tall. The hole is 3.3 m away from the edge of the roof (label this in the figure). The roof is perfectly level all the way across. a) Isabella strikes the ball causing it to launch from the ground with an initial velocity of 22.70 m/s and at an angle of θ = 72.00 . Is it possible for Isabella to make her shot to the roof? Ignore wind resistance for part (a). b) Assuming that Isabella’s shot from part (a) made it to the roof and the shot is line up to go into the hole that is 3.30 m away from the edge of the roof. The golf ball has a mass of 45.93 g, and experiences a friction force of f=0.133 N. If the ball’s speed is larger than 5.90 m/s when at the hole it will be moving too fast and not go in. Will Isabella’s shot go into the hole? Explain why she does make or does not make it in the hole.arrow_forwardA projectile is launched from ground level at an angle θ to the top of a cliff which is 195 m away and 155 m high. If the projectile lands right on the cliff edge 7.6 s after it is fired, find the initial velocity of the projectile.arrow_forwardProblem 38. The distance from the pitcher's mound to home plate is 18.4 m. The mound is 0.2 m above the level of the field. A pitcher throws a fastball with an initial speed of 35 m/s. At the moment the ball leaves the pitcher's hand, it is 2.2 m above the mound. What should be the angle between the ball's initial velocity and the horizontal if the ball is to cross the plate a height of 1 m above the ground? (Neglect air resistance.)arrow_forward
- A boy is standing from the top of a cliff 8 m from the ground and he has a bow which is aimed 40 degrees from the horizontal. He can release the bow with an initial velocity of 15 m/s. An animal is below the cliff and is moving towards the boy at a velocity of 5 m/s. For the bow to hit the animal, at what distance D should the animal be when the bow is fired?arrow_forwardA garden hose is laying on the ground while the valve is opened. The nozzle of the hose is shooting the water upwards in an angle of 21°. The initial speed of the water spray is 20 m/s. There is a wall 8.0 m away. How high on the wall the water spray hits?arrow_forwardA batter hits the baseball A with an initial velocity of vo = 98 ft/sec directly toward fielder B at an angle of 38° to the horizontal; the initial position of the ball is 2.2 ft above ground level. Fielder B requires 0.46 sec to judge where the ball should be caught and begins moving to that position with constant speed. Because of great experience, fielder B chooses his running speed so that he arrives at the "catch position" simultaneously with the baseball. The catch position is the field location at which the ball altitude is 7.9 ft. Determine the velocity of the ball relative to the fielder at the instant the catch is made. Vo 438° 2.2¹ Answer: VA/B = (i 246' i+ i j) ft/secarrow_forward
