D.) The pauT taken irom TIILUNG he Dail unur he Tmaximum nieignt is just
symmetrical with the path taken from the maximum height to the
ground. Hence, we can get the range by doubling the x displacement
when the ball is at its maximum y value. We will use formula 4
1
x = Vixt +5a;t
x = (5 cos 53.1) (0.41) +(0)(0.41)²
x = 1.23 m
Range = 2x = 2 (1.23) = 2.46 m
Start answering here:
1. A ball is thrown horizontally from a building 75.0 m high with a speed of 25.0
m/s. Fin the (a) vertical and horizontal components of the ball's initial velocity,
(b) time of flight, and (c) velocity when the ball will strike the ground.
2. A golf player hits a ball that leaves its initial location at speed of 40.0 m/s at an
angle of 38°. Find the (a) time the ball reaches the highest point of its flight, and
its height h at this time, and (b) horizontal distance from the starting point to
where the ball hits the ground.
