Question

A baseball accelerates downward at 9.8 m/s squared. If the gravitational force acting on the baseball is 1.4 N what is the baseballs mass?

Answer 1

We are given that a baseball accelerates at a rate equal to 9.8 meters by second squared. And we are given that the force acting is 1.4N. We are asked to determine the mass of the ball. We can use Newton's second law since this related the force exerted to an object with its mass and acceleration in the following formula:

`F=ma`

We can solve for the mass "m" by dividing both sides by the acceleration "a":

`(F)/(a)=m`

Replacing the values:

`(1.4N)/(9.8(m)/(s^2))=m`

Solving the operations:

Therefore, the mass of the ball is 1.43 kilograms.
