A golf ball resting on the ground is struck by a golf club and given an initial velocity of 50 m/s at an angle of 30° above the horizontal. The ball heads toward a fence12 meters high at the end of the golf course, which is 200 meters away from the point at which the golf ball was struck. Neglect any air resistance that may be acting on the golfball. 50 m/s 12 m 30 200 m c) Calculate the time it takes for the ball to reach the plane of the fence. * Your answer d) Will the ball hit the fence or pass over it? Justify your answer by providing the height of the ball at a range of 200 m. *

A projectile is fired at 30° above the horizontal at a speed of 200 m/s.  a) Find the time of flight or “hang time.” (how long is it in the air?) (calculate in seconds) b) Find the range of the projectile. (calculate in M)

A projectile 10.0 m above ground is fired horizontally with an initial speed of 12.0 m/s the projectile in air = 1.43s the projectile travel before hitting the ground = 17.2 m The fired cannon at several different initial speeds and its corresponding ranges initial speed range 13.0 18.6 14.0 20.0 15.0 21.5 16.0 22.9 17.0 24.3 a. Does range increase linearly with the initial speed? Explain. b. Find the time of flight t and the correlation coefficient r : c. Find the value of g

A fighter plane moving 233 m/s horizontally fires a projectile with speed 59 m/s in a forward direction 30.0° below the horizontal. What is the speed of the projectile with respect to a stationary observer on the ground? a) 249 m/s Ob) 2660 m/s c) 288 m/s d) 286 m/s
