Why is the law of gravity a scientific law

Yuri [45]

An object in motion will stay in motion unless acted upon another force.

Newton used this to prove that gravity existed. Without an unseen force, we could throw a ball and it would go on forever correct? Unless there was something to pull it down, in this case, gravity.

Answer:

$F_{braking}=337299 pdl$

Explanation:

Impulse-Momentum relation:

$I=\Delta p\\ F_{total}*t=m(v_{f}-v{o})$

$F_{total}=-F_{braking}+mgsin{\theta}$

We solve the equations in order to find the braking force:

$F_{braking}=m(v_{o}-v{f})/t+mgsin{\theta}=17926(75.6-30.3)/6.4+17926*32.17*sin21.4=337299 pdl$

Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions here.

a=Δω/Δt
a=2π*Δf/Δt
a=2π*(f2-f1)/Δt

f1=f2-a*Δt/2π
f2=800/60 rev/sec
a=-42 rad/sec^2
Δt=1.75sec
so f1=25 rev/sec
f1=1500 rev/min
