Question

part a: How long will it take a ball to reach the ground if it is thrown out of a window with an initial velocity of +16.0 m/s. The window is 35.0 m above the ground. part b: Repeat the last problem, but this time assume it is thrown downwards at a speed of 16.0 m/s, instead of upwards.

Answer 1

Answer: 1.49 seconds

Step-by-step explanation:

Using Equation of motion = ut+½ at²

given u= 16 m/s, s= 35m and the acceleration due to gravity on the ball falling down is 9.8m/s². On solving the quadratic Equation in t , we get t= 1.4
