Question

A 9.00 kg object is dropped from rest near the surface of an unknown planet and begins to accelerate at 6.00 m/s2. What is the weight of the object on the unknown planet? (*Remember* F=ma)

a
216 N
b
9 N
c
88 N
d
54 N

Answer 1

The weight of an object is the force of gravity acting on it, which is typically represented by the equation Fg = mg, where m is the mass of the object and g is the acceleration due to gravity. However, on different planets, the acceleration due to gravity (g) can be different.

To solve this problem, we can use the formula F = ma, where F is the net force acting on the object, m is its mass, and a is its acceleration. We know that the object has a mass of 9.00 kg and is accelerating at 6.00 m/s2. Plugging these values into the formula, we get:

F = ma
F = (9.00 kg)(6.00 m/s2)
F = 54 N

Therefore, the weight of the object on the unknown planet is 54 N, which is answer choice (d).
