Question

A 90 kg body is taken to a planet where the acceleration due to
gravity is 2.5 times that of the earth. What is the weight of this body
on the surface of this planet? Take g = 10 m/s?.

Answer 1

Answer:

2250N

Explanation:

W= mg,

where W= weight

m= mass

g= acceleration due to gravity

Given that the body is 90kg, m= 90kg.

Acceleration due to gravity of planet

= 2.5(10)

= 25 m/s²

Weight of body on planet

= 90(25)

= 2250N

*Mass is the amount of matter an object has and is constant (same on earth and the planet).

Answer 2

Answer:

Here

mass=90kg

time=2.5second

acceleration due to gravity=10m/s

now,,,

Force=???

Force=mass*acceleration

Force=90*10

Force=900N
