Orbits are the result of a perfect balance between the forward motion of a body in space, such as a planet or moon, and the pull of gravity on it from another body in space, such as a large planet or star. An object with a lot of mass goes forward and wants to keep going forward; however, the gravity of another body in space pulls it in. There is a continuous tug-of-war between the one object wanting to go forward and away and the other wanting to pull it in.
The magnitude of the force required to stop the weight in 0.333 seconds is 67.6 N.
<h3>
Magnitude of required force to stop the weight</h3>
The magnitude of the force required to stop the weight in 0.333 seconds is calculated by applying Newton's second law of motion as shown below;
F = ma
F = m(v/t)
F = (mv)/t
F = (5 x 4.5)/0.333
F = 67.6 N
Thus, the magnitude of the force required to stop the weight in 0.333 seconds is 67.6 N.

For basic it would be a proton and a neutron to create a nucleus and outside are electrons surrounding it.
KE= 0.5mv^2
165J= 0.5×(825kg+1kg)×v^2
165J = 413kg×v^2
v^2=165J÷413kg
v^2=0.39952 m^2/s^2 (5s.f.)
v= √0.39952= 0.632 m/s (3.s.f.)
