Answer:
The initial velocity of the ball is +38.0 m/s. The final velocity is -27.0 m/s.
momentum = mass x velocity
(mass x final velocity) – (mass x initial velocity)
(1.5)(-27) – (1.5)(38) = -97.5
The impulse applied to the ball is -97.5 kg m/s
impulse = force x time interval
force = impulse/time interval
-97.5/0.45 s = - 216.6
The force applied was 216.6 N.

The electrons are not found in the nucleus. Electrons are in constant movement in the electron cloud. The only sub-atomic particles in the nucleus are the protons and neutrons.
Answer:
You have to calculate
Explanation:
Work is done when a force that is applied to an object moves that object. The work is calculated by multiplying the force by the amount of movement of an object (W = F * d). A force of 10 newtons, that moves an object 3 meters, does 30 n-m of work.
