1.7 million people are killed
(a) work=Fd
<span>345x24=8280J </span>
<span>(b) work=Force of friction*d </span>
<span>Force of friction =coefficient*normal force=.22x1.5x10^3=330 </span>
<span>330*d=7920J </span>
<span>(c) net work =8280-7920=360J</span>
Newton's 2nd law of motion:
Net Force = (mass) x (acceleration) .
The law shows the relationship among an object's mass
and acceleration, and the net force acting on it.
If you know any two of the quantities in the formula,
the law can be used to calculate the third one.
A scientific theory is something that can not be proven through experimentation, hope this helps
It’s true now say thank you
