Question

A ping pong ball rolls off a table at 2. 33 m/s. What is the magnitude of the ball's velocity after 0. 428 s? (Ignore direction)

(unit =m/s)​

Answer 1

Step-by-step explanation:

It is still traveling at 2.33 m/s horizontally

the vertical velocity is given by v = at = 9.81 * .428 = 4.2 m/s

total magnitude = sqrt ( 2.33^2 + 4.2^2) = 4.8 m/s
