Question

Acceleration due to gravity on planet is 1.96 if safe to jump from height 3m on earth correspnding height on planet?

Answer 1

Answer:

Initial velocity = u = 0

acceleration = 9.8

vertical distance = 3m

final velocity = v = 0

so,

v² - u²= 2as

v² - 0 = 2 x 9.8 x 3

v= 7.7

in the 2nd situation;

u = 0

v= √58.8

a= 9.8

applying the same formula

58.8 - 0 = 2 x 9.8 x s

s = 1.5 m
