A0.25 kg baseball is in contact with a bat for 0.0075 s and exerts a force of 18,500 n. what impulse is delivered to the ball? 33 kg • 140 kg • 4600 kg • 74,000 kg •

Mass of base ball = 0.25kg

Time = t = 0.0075/s

Force = F = 18,500N

Impulse = J = ?

Formula = Impulse = Force x time

= 18,500x0.0075

= 138.75 N-S

Rounded: 140 kg

Impulse, J = 140 kg m/s

Explanation:

It is given that,

Mass of the baseball, m = 0.25 kg

Force exerted on the baseball, F = 18,500 N

Time of contact of baseball and bat is, t = 0.0075 s

We have to find the impulse delivered to the bat. Impulse is defined as the product of force and time. It is also equivalent to change in momentum.

So, J = F × t

J = 138.75 N-s

or

J = 140 kg m/s

Hence, this is the required solution.

radiation

explanation:

heat is transmitted by radiation

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
