Question

A 9.00 kg object is released from rest near the surface of an unidentified planet, exhibiting an acceleration of 6.00 m/s². What is the object's weight on the unidentified planet?
A. 9.00 N
B. 88.0 N
C. 216 N
D. 54.0 N

Answer 1

To find the weight of the object on the unidentified planet, we can use the formula for weight, which is given by:

\[
\text{Weight} = \text{mass} \times \text{acceleration due to gravity}
\]

In this case, the mass (m) of the object is 9.00 kg, and the acceleration due to gravity (a) on this unidentified planet is 6.00 m/s².

Substituting the values into the formula gives:

\[
\text{Weight} = 9.00 \, \text{kg} \times 6.00 \, \text{m/s}² = 54.0 \, \text{N}
\]

Thus, the object's weight on the unidentified planet is:

**D. 54.0 N**
