Question

A 10.-kilogram object, starting from rest, slides down a frictionless incline with a constant acceleration of 2.0 m/sec2 for four seconds. What is the approximate weight of the object? A) 1 N B) 10 N C) 100 N D) 1,000 N

Answer 1

Answer:

C) 100N

Explanation:

Formula for calculating the Weight of an object is expressed as;

Weight = mass × acceleration due to gravity

Given

Mass of the object = 10kg

Acceleration due to gravity = 9.81m/s²

Substitute into the formula above

Weight = 10×9.81

Weight = 98.1N

Hence the approximate weight of the object is 100N

Answer 2

C) 100N

Given:

Mass of the object = 10kg

Acceleration due to gravity = 9.81m/s²

Weight is a measure of the force of gravity pulling down on an object. It depends on the object's mass and the acceleration due to gravity, which is 9.8 m/s² on Earth.

Formula for calculating the Weight of an object is expressed as;

Weight = mass × acceleration due to gravity

On substituting the values in the above formula:

Weight = 10×9.81

Weight = 98.1N

Hence, the approximate weight of the object is 100N.

Therefore, the correct option is option C.
