Question

With what magnitude of force does a ball of mass 0.75 kilograms need to be hit so that it accelerates at the rate of 25 meters/second2? Assume that the ball undergoes motion along a straight line.

Answer 1

Assume that the ball undergoes motion along a straight line. ... F = m A Force = (mass) x (acceleration) The question tells you the mass and the acceleration. All YOU have to do is take the numbers and pluggum into Newton's 2nd law. F = m A = (0.75 kg) (25 m/s²) = (0.75 x 25) kg-m/s² = 18.75 Newtons .

i looked it up ok

Answer 2

A ball of mass 0.75 kilograms needs to be hit so that it accelerates at the rate of 25
`meters/second^2` assuming that the ball undergoes motion along a straight line and the mount of Force required is 18.75 newton.

Step-by-step explanation:

According to Newton`s 2nd law F=Ma,

where M mass of the object, a- Acceleration due to gravity.

Given-

Mass (m) = 0.75 kg

Acceleration (a) = 25
`m/s^2`

We know That, Force = mass × acceleration

Substituting the given values , we get

F = 0.75 × 25

F= 18.75 N
