Question

An object is dropped, with no
initial velocity, near the surface
of planet Manta reaches
a speed of 21 meters/seconds
in 30 seconds Planet Manta
has a mass of 2300
Find out
(a) what is the acceleration
acting on the doject
(b) what is the radius of​

Answer 1

Answer:

Explanation:

v=at   since u=0

a=21/30=0.7 ms-2

a=GM/$R^{2}$

G=6.67* $10^{-11}$

M=2300

a=0.7

R can be found using the above equation
