We can solve the problem by using Newton's second law of motion:
[tex]F=ma[/tex]
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:
[tex]F=ma=(13.5 kg)(9.5 m/s^2)=128.25 N[/tex]
So, the correct answer is
D. 128.25 N
Answer: The correct answer is option D.
Explanation:
Mass of an object = 13.5 kg
Rate of the acceleration = [tex]9.5 m/s^2[/tex]
[tex]Force=Mass\times Acceleration=ma[/tex](Newton's second law of motion)
[tex]Force=13.5 kg\times 9.5 m/s^2=128.25 kg m/s^2=128.25 Newtons[/tex]
128.25 Newtons of force is required to accelerate it to a rate of [tex] 9.5 m/s^[/tex].
Hence,the correct answer is option D.
