<h2>
Answer: F=32.2m</h2>
Explanation:
According Newton's 2nd Law of Motion the force is directly proportional to the mass and to the acceleration of a body:
(1)
When we talk about the force of gravity on an object (the weight) the constant acceleration is due gravity, this means:
(2)
Substituting (2) in (1):
(3)
This means the equation that best represents the force on an object due to gravity according to its mass, among the given options is:
Answer:
<h2>132 N</h2>
Explanation:
The force acting on an object given it's mass and acceleration can be found by using the formula
force = mass × acceleration
From the question we have
force = 66 × 2
We have the final answer as
<h3>132 N</h3>
