Question

If an astronaut has a mass of 112 kg, what is his weight on Earth where the acceleration due to gravity is 9.8m/s2?

Answer 1

Answer:

His weight on Earth is 1097.6N

Explanation:

You have to apply Newton's Second Law, F = m×a where F is force, m is mass and a is accerleration. Then, you have to substitute the following values into the equation :

$f = m \times a$

Let m = 112kg,

Let a = 9.8m/s²,

$f = 112 \times 9.8$

$f = 1097.6$
