Question:
A baloon is moving vertically upward with a velocity of 4m/s .vWhen it reaches a height of 40m then a ball dropped from it. calculate how much distance it cover when ball strikes the earths surface .
Answer:
160m
Explanation:
Given => h = 40m
u = 4m/s(velocity of baloon)
a = 0m/s (baloon is mass less)
S =?
So,
'by 2nd equation of motion
S = ut + 1/2 at^2
S = uh + 1/2ah
S = 4 * 40
S = 160m
Hope you undestand
