Question

16. An object has a mass of 13.5 kilograms. What force is required to accelerate it to a rate of 9.5 m/s2?

Answer 1

Answer: The correct answer is option D.

Explanation:

Mass of an object = 13.5 kg

Rate of the acceleration = $9.5 m/s^2$

$Force=Mass\times Acceleration=ma$(Newton's second law of motion)

$Force=13.5 kg\times 9.5 m/s^2=128.25 kg m/s^2=128.25 Newtons$

128.25 Newtons of force is required to accelerate it to a rate of $9.5 m/s^$.

Hence,the correct answer is option D.

Answer 2

We can solve the problem by using Newton's second law of motion:

$F=ma$

where F is the force required to accelerate the object, m is its mass, and a is the acceleration.

In this problem, we are told that the mass of the object is m=13.5 kg, while its acceleration is a=9.5 m/s^2. Substituting these data into the equation, we find the force required to produce these acceleration:

$F=ma=(13.5 kg)(9.5 m/s^2)=128.25 N$

So, the correct answer is

D. 128.25 N
