The acceleration due to gravity on planet X is
one-fifth that on the surface of the earth.

distance from rest on earth, how long would
it take to fall the same distance on planet X?

The time taken for the object to fall the same distance in planet X is determined as 8.5 seconds.

Time of motion of the object planet X

The time taken for the object to fall the same distance on planet X is calculated as follows;

t = √2h/g

where;

  • h is height of fall
  • g is acceleration due to gravity
  • t is time of motion

t² = 2h/g

gt² = 2h

g₁t₁² = g₂t₂²

t₂² = g₁t₁²/g₂

t₂² = (g₁ x 3.8²) / (0.2g₁)

not e one-fifth = 1/5 = 0.2

t₂² = 72.2

t₂ = √72.2

t₂ = 8.5 seconds

Thus, time taken for the object to fall the same distance in planet X is determined as 8.5 seconds.
