1. A player lines up to kick a 40 m goal. In the first attempt, the ball has an initial velocity of 20 m/s at angle of 55.0 degrees. The goal posts are 3 m high. Once the ball passes above the field goal post (i.e., after it has travelled 40 m in the horizontal direction), it is deemed successful. (a) Determine if the goal kicker's first attempt is successful. (b) If the kicker changes the angle of kicking to 30 degrees and the initial velocity so that it JUST reaches the goal post. Determine the new initial velocity of ball.

A regulation volleyball court measures L = 18.0 meters in length and d = 2.43 meters in height. A volleyball player hits the ball from a height of h = 1.50 m just over the backline, and the initial velocity of the ball creates an angle of q = 30° with the ground. At what initial speed must the ball be struck such that it barely clears the net?
Cuban tree frogs are skilled jumpers. They can launch themselves at 4.5 meters per second at an angle of 26o above horizontal. Assuming the frog is jumping on level ground, what is the maximum height above the ground that the frog will achieve? 0.95 m 1.2 m 0.20 m 0.61 m
A punter kicks a football at an angle of 30 degrees with the horizontal at an initial speed of 15 m/s. Where should a punt returner position himself to catch the ball just before it strikes the ground?
You buy a plastic dart gun, and being a clever physics student you decide to do a quick calculation to find its maximum horizontal range. You shoot the gun straight up, and it takes 3.6 ss for the dart to land back at the barrel.
A football kicker is attempting a field goal from 39 m out. The ball is kicked and just clears thelower bar with a time of flight of 2.6 s. If the angle of the kick was 45°, what was the initial speed ofthe ball?A) 21.2 m/s B) 11.9 m/s C) 30.9 m/s D) 2.2 m/s
One of the fastest recorded pitches in major league baseball, thrown by Tim Lincecum in 2009, was clocked at 101.0 mi/h (Fig. P3.8). If a pitch were thrown horizontally with this velocity, how far would the ball fall vertically by the time it reached home plate, 60.5 ft away? Figure P3.8 Tim Lincecum throws a baseball.
A World War II bomber flies horizontally over level terrain with a speed of 275 m/s relative to the ground and at an altitude of 3.00 km The bombardier releases one bomb. (a) How far does the bomb travel horizontally between it release and its impact on the ground? Ignore the effects of air resistance. (b) The pilot maintains the planes original course, altitude, and speed through a storm of flak. Where is the plane when the bomb hits the ground? (c) The bomb hits the target seen in the telescopic bombsight at the moment of the bombs release. At what angle from tin- vertical was the bombsight set?
A cannon with a muzzle speed of 1 000 m/s is used to start an avalanche on a mountain slope. The target is 2 000 m from the cannon horizontally and 800 m above the cannon. At what angle, above the horizontal, should the cannon be fired?
A projectile is launched on the Earth with a certain initial velocity and moves without air resistance. Another projectile is launched with the same initial velocity on the Moon, where the acceleration due to gravity is one-sixth as large. How does the range of the projectile on the Moon compare with that of the projectile on the Earth? (a) It is one-sixth as large, (b) It is the same, (c) It is V5 limes larger, (d) It is 6 times larger, (e) It is 6limes larger.
