Problem 2: A ball is dropped from rest from a height of 6 meters, Find the time it takes the ball
to fall. Find the velocity of the ball just before it hits the earth. Assume no air resistance and
that acceleration due to gravity (g) is 9.8 m/s/s.

Respuesta :

Answer:

1.11 s , 10.88 m/s

Step-by-step explanation:

Initial velocity and air resistance = 0

Time to fall : s = 1/2 gt²

6 = 1/2 * 9.8 * t²

t² = 1.224

t = 1.11 s

final velocity = initial velocity + gt

                    = 0 + 9.8 * 1.11

                    = 10.88 m/s
