Question

A stone is thrown down off a bridge with a velocity of 5.6 m/s. What is its velocity after 3 seconds have passed?

Answer 1

Answer:35 m/s

Explanation:Ball is going down with velocity 5.6 m/s hence u=-5.6

a=-g=-9.8(acceleration is in downward direction)

t=3 second

V=u+at

V=-5.6 -9.8(3)

V=-5.6 -29.4

V=35m/s
