Question

Newton's second law states that F= m xa (Force is mass times acceleration). Which example would have the GREATEST

acceleration?

Answer 1

Newton's second law states that
`F=m * a` (Force is mass times acceleration). Out of the given options, “a 10 kg ball thrown with a 50 Newton force”, an example have the greatest acceleration.

Explanation:

To do the calculation, we already have the formula given derived from Newton’s second law of motion. To know the acceleration, we can simply modify the formula as,

`\text { Force }=\text { mass } * \text { acceleration }`

`\text {acceleration}=\frac{\text {Force}}{\text {mass}}`

For the 10kg ball threw in 50N, we have mass = 10 kg and Force = 50 N

Acceleration =
`(50)/(10)=5 \mathrm{m} / \mathrm{s}^(2)`

Similarly for 1 kg ball threw in 0.5N, substituting the values, we get ,

Acceleration =
`(0.5)/(1) = 0.5 \mathrm{m} / \mathrm{s}^(2)`

For launching 50kg student by catapult of 100N,

acceleration =
`(100)/(50)=2 m / s^(2)`

For accelerating 500 kg car in 1000N engine,

acceleration =
`(1000)/(500) = 2 m / s^(2)`
