On another planet gravity has a value of 5.5 m/s. If an object is dropped how long will it take to fall 53 m?

4.4 seconds

Explanation:

Given:

a = - 5.5 m/s²

v₀ = 0 m/s

y₀ = 53 m

y = 0 m

Find: t

y = y₀ + v₀ t + ½ at²

0 = 53 + 0 + ½ (-5.5) t²

0 = 53 - 2.75 t²

t = 4.39

Rounded to two significant figures, it takes 4.4 seconds for the object to land.
