Answer:
Newton's Second Law is applied because of the acceleration caused by natural forces as the egg is plummeting to the earth. And the amount of acceleration the egg has will be largely affected by the amount of force Mr. Baker uses to hurl the egg to the ground.

Answer:
The net force is 392N, pointing down.
Explanation:
The net force is the sum of all forces acting on the rock, namely the gravity ("+" acting downward) and the friction force due to air resistance ("-" acting upward):
The net force is 392N and pointing down (positive)/
Given;
redistivity =1.68/100000000W.m
diameter =0.40in
=0.01016m
length =1m
resistance =?
redistivity =resistance×area/lenght
restance=resistivity × length /area
so, resistance =1.6535/1000000 ohmn
Answer:
rpm= 916.7436 rev/min
Explanation:
First determine the perimeter of the wheel, to know the horizontal distance it travels in a revolution:
perimeter= π×diameter= π × 22 inches × 0.0254(m/inche)= 1.7555m
Time we divide the speed of the car, which is the distance traveled horizontally over time unit, by the perimeter of the wheel that is the horizontal distance traveled in a revolution, this dates us the revolutions over the time unit:
revolutions per time= velocity/perimeter
velocity= (60 mi/hr) × (1609.34m/mi) = 96560m/h
revolutions per time= (96560.6m/h) / (1.7555m)= 55004.614 rev/hr
rpm= (55004.614 rev/hr) × (hr/60min)= 916.7436 rev/min
An object will remain at rest of maintain constant straight-line motion unless acted on by a force that is c. unbalanced
