The application of physics is everywhere. In school, physics applications can be seen in other learning areas like physical education (P.E). When you are watching a soccer play-off when the soccer player kicked the ball from ground level. You are given a chance to kick a soccer ball at an initial velocity of 80 m/s to reach the goal with a distance of 300 m. At what angle do you intend to kick the ball?

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 projectile is thrown from the top of a building with an initial velocity of 30 m/s in thehorizontal direction. If the top of the building is 30 m above the ground, a) how long isthe projectile in the air? b) With what speed and angle will the projectile be moving justbefore it strikes the ground? (Hint: final speed = 38.6 m/s)
A Wide Reciever is running along the sideline straight towards the goal at a constant speed. When he is 27 m away from the goal line he cathces the ball, but theire is a cornerback 12 m behind him moving with a connstant speed of vc=9.0 m/s what speed should the wide reveiver have to make sure he reaches the goal line just as the cornerback reaches him.
. Prove that the trajectory of a projectile is parabolic, havingthe form y = ax + bx2. To obtain this expression, solve theequation x = v0xt for t and substitute it into the expressionfor y = v0yt – (1 / 2)gt2(These equations describe the xand y positions of a projectile that starts at the origin.) Youshould obtain an equation of the form y = ax + bx2 wherea and b are constants

Eddie Manalak is a Filipino stuntman, he wishes to cross the 520m distance between two tall buildings by being shot from a cannon. He wishes to be launched at 60° to the horizontal so that he can spend more time in waving to the crowd. With what speed must he be launched? ANS. 76.7 m/s
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…
