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?

A. 81.00 N
B. 173.75 N
C. 132.30 N
D. 128.25 N

Answer 1

Answer: The correct answer is option D.

Step-by-step explanation:

Mass of an object = 13.5 kg

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

`Force=Mass* Acceleration=ma`(Newton's second law of motion)

`Force=13.5 kg* 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
