Answer:
-5.396Joules
Explanation:
Work is said to be done when a force causes a body to move through a distance and acts in the direction of the force.
Work done = Force × Distance
Given force = mg
Force = 2.20×9.81
Force applied on the string = 21.58N
Distance will be the difference in height = 4.75-5.00
= 0.25m
Negative work done on the pendulum during the first entirely oscillation = 21.58×0.25
= -5.396Joules

Answer:
n/(FG) = 3.
Explanation:
<u>At the top of the loop-the-loop, the normal force is directed downwards</u> as well as the weight of the car. So, the total net force of the car is
<u>By Newton's Second Law, this force is equal to the centripetal force</u>, because the car is making circular motion in the loop.
The critical speed is the minimum speed at which the car does not fall. So, at the critical speed the normal force is zero.
If the car is moving twice the critical speed, then
Finally, the ratio of the normal force to the gravitational force is
