- (spring constant) (new length of spring - original length of spring) = Force applied to spring.
that is
-kx=F
Did you only have how far the cart traveled? No mass or acceleration or speed or time taken?
Answer: b)
Explanation: L has units of Kg.m^2/s
P has units of Kg . m /s
However these vectors are in different plane, L is perpendicular to the plane form by the velocity and position vector from the center of the circle.
Answer: Just a few examples are the tension in the rope on a tether ball, the force of Earth's gravity on the Moon, friction between roller skates and a rink floor, a banked roadway's force on a car, and forces on the tube of a spinning centrifuge. Any net force causing uniform circular motion is called a centripetal force.
This is the Conservation of energy. We say energy is conserved because none is lost in the process.
