Question

NEED HELP!?Which of the following combinations would result in the greatest acceleration?

A 60N & 2.0kg
B 1N & 0.20kg
C 5N & 0.35 kg
D 12N and 1.0 kg

Answer 1

The greatest acceleration is presented in option A 60N & 2.0kg

Step-by-step explanation:

The second Newton's law relates the net force F exerted on an object of mass m and the acceleration it has by the equation:

F=m.a

The acceleration is found by solving the equation for a:

`\displaystyle a=(F)/(m)`

Let's compare the different options and choose the greatest acceleration.

A F= 60 N, m= 2 Kg.

`\displaystyle a=(60)/(2)=30\ m/s^2`

B F= 1 N, m= 0.20 Kg.

`\displaystyle a=(1)/(0.2)=5\ m/s^2`

C F= 5 N, m= 0.35 Kg.

`\displaystyle a=(5)/(0.35)=14.29\ m/s^2`

D F= 12 N, m= 1 Kg.

`\displaystyle a=(12)/(1)=12\ m/s^2`

The greatest acceleration is presented in option A 60N & 2.0kg
