Question

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

Answer 1

Newton's second law states that $F=m \times a$ (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,

                  $\text { Force }=\text { mass } \times \text { acceleration }$

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

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

Acceleration =  $\frac{50}{10}=5 \mathrm{m} / \mathrm{s}^{2}$

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

Acceleration =  $\frac{0.5}{1} = 0.5 \mathrm{m} / \mathrm{s}^{2}$

For launching 50kg student by catapult of 100N,

acceleration = $\frac{100}{50}=2 m / s^{2}$

For accelerating 500 kg car in 1000N engine,

acceleration = $\frac{1000}{500} = 2 m / s^{2}$
