Question

A person who is 1.2 m tall throws a ball with a speed of 23 m/s at an angle of 44 degrees above the horizontal, as shown in the diagram below.
h = 1.2 mv = 23 m/s, θ = 44 degrees

Use the acceleration due to gravity as g = 10 m/s2.

 

What is the ball's speed (the magnitude of the velocity) the instant before it hits the ground?
 m/s

  Tries 0/2  


What is the time of flight; that is, the time taken for the ball to hit the ground after it has left the person's hand?
 s
