How much force (in Newtons) does a baseball pitcher have to exert on a 250g baseball to make it accelerate to 50 m/s the
Instant that it leaves his hand?

Answer 1

Force = 12.5 Newton

Step-by-step explanation:

Given the following data;

Mass = 250 g to kilograms = 250/1000 = 0.25 kg

Acceleration = 50 m/s²

To find the force;

Newton's Second Law of Motion states that the acceleration of a physical object is directly proportional to the net force acting on the physical object and inversely proportional to its mass.

Mathematically, it is given by the formula;

`Acceleration = \frac {Net \; force}{mass}`

Making force the subject of formula, we have;

`Force = mass * acceleration`

Substituting into the formula, we have

`Force = 0.25 * 50`

Force = 12.5 Newton
