Two balls A and B of masses 100 grams and 300 grams respectively are pushed horizontally from a table of height 3 meters. Ball has is pushed so that its initial velocity is 10 m/s and ball B is pushed so that its initial velocity is 15 m/s. a. Find the time it takes each ball to hit the ground. b. What is the difference in the distance between the points of impact of the two balls on the ground?

9. Two balls A and B of masses 100 grams and 300 grams respectively are pushed horizontally
from a table of height 3 meters. Ball has is pushed so that its initial velocity is 10 m/s and ball
B is pushed so that its initial velocity is 15 m/s.
a. Find the time it takes each ball to hit the ground.
b. What is the difference in the distance between the points of impact of the two ball
on the ground?
Formula
Vx = Vo cos 0
Vy = Vo sin 0 – gt
x = Vo cos et
y = Vo sin Ot –
