Question

A baseball is dropped from rest from a height of 1.6 m from the ground. What is its velocity when it hits the ground? O a.3.1 m/s O b.9.8 m/s O c.5.6 m/s O d. 2.1 m/s O e.7.3 m/s & QUESTION 2 Continuing from the previous problem, how long was it in the air? O a. 6.2 s O b.4.3 OC.5.1 s O d.1.0 S O e.0.6s

Answer 1

Let beforce hits the ground then o is the velocity V = V 2gh height where h of the ball - 1.6m U = V2x9.8 x 1.5 m/s 5.6 m/s g

for at second 27 let the ball Let the ball crass in. Grass in air then gt v 5.6 U S 0.65 => to 9.8) t = 0.63
