After a golf ball is hit it takes off with an initial speed of 26.2 m/s and at an angle of 39.5° with respect to the horizontal. The golf field is flat and horizontal. Neglecting air resistance how far will the golf ball fly? How high will the golf ball rise? 1.42×101 m You are correct. How much time will the ball spend in the air? How far would the ball fly if the initial speed was doubled? How much time would the ball spend in the air in this second case?
The jet accelerates uniformly, and during that time, the pendulum oscillates about the equilibrium position shown by the solid line, with D = 0.370 m. find the magnitude of the plane's acceleration.
A double speed trap is set up on a freeway. One police cruiser is hidden behind a billboard, and another is some distance away under a bridge. As a sedan passes by the first cruiser, its speed is measured to be 99.7 mph.
