Question

Baseball Player Throws A Ball Giving It A Change In Momentum Of 6.5 Kg.m/s. Over 90 Ms. What Is The Magnitude Of The Net Force On The Ball?

Answer 1

The atomic number or proton number of a chemical element is the number of protons found in the nucleus of every atom of that element. The atomic number uniquely identifies a chemical element. It is identical to the charge number of the nucleusAtom, smallest unit into which matter can be divided without the release of electrically charged particles. It also is the smallest unit of matter that has the characteristic properties of a chemical element. As such, the atom is the basic building block of chemistry.

Answer 2

The Magnitude Of The Net Force On The Ball is 72.2N.

Given:

Baseball Player Throws A Ball Giving It A Change In Momentum Of 6.5 Kg.m/s.

To Find:

The Magnitude Of The Net Force On The Ball.

Solution:

To find the Magnitude Of The Net Force On The Ball we will follow the following steps:

As we know,

Change in momentum = force × time

Now,

According to the question:

Change in momentum = 6.5kg m/s

Time = 90ms =

$90 \times {10}^{ - 3} s$

$(1ms = {10}^{ - 3}s )$

Now,

In putting values we get,

$6.5 = force \times 90 \times {10}^{ - 3}$

$force = \frac{6.5}{90 \times {10}^{ - 3} } = \frac{650}{9} = 72.2N$

Henceforth, The Magnitude Of The Net Force On The Ball is 72.2N.
