Question

Gunter the weightlifter can lift a 230.0-kg barbell overhead on Earth. The acceleration due to gravity on the sun is 274 m/s2. a) Would the barbells be heavier on the sun or on Earth? b) How much (in newtons) would the barbells weigh on the sun (if it were possible to stand on the sun without melting)?

Answer 1

a) heavier on sun

b) 63.0 kN

Step-by-step explanation:

The weight is directly related to gravity, so because the sun has a bigger gravity than earth the barbell will be heavier on the sun.

the force exerted by the gravity is defined as:

`F_(g)=m*g\\F_g=230.0kg*274m/s^2\\F_g=63.0kN`
