If you weigh 150 lbs. on the surface of Earth, how much would you weigh on Venus? On Mars?

weight on Venus = 604.15 N

weight on Venus = 252.01 N

Explanation:

Given:

Weight on the earth, W = 150 lbs

now,

1 lbs = 4.45 N

thus,

W = 150 * 4.45 = 667.5 N

now, mass on the earth, m = 667.5/9.8 = 68.11 kg

now,

⇒ weight on Venus,

the acceleration due to gravity on venus = 8.87 m/s²

thus,

weight on Venus = mass * acceleration due to gravity on venus

or

weight on Venus = 68.11 * 8.87 = 604.15 N

⇒ weight on mars,

the acceleration due to gravity on mars = 3.70 m/s²

thus,

weight on Venus = mass * acceleration due to gravity on venus

or

weight on Venus = 68.11 * 3.70 = 252.01 N
