A pendulum bob has a mass of 1 kg. The length of the pendulum is 2 m. The bob is pulled to one side to an angle of
10° from the vertical.
a) What is the velocity of the pendulum bob as it swings
through its lowest point?
b) What is the angular velocity of the pendulum bob?​

The force applied to a spring equals the product of the spring constant and the displacement.

Explanation:

From Hooke's law, the force required to extend or compress a spring by a distance is proportional to the distance. This means extension is proportional to force.

Mathematically it is stated as;

F= -k*x  where k is the spring constant and x is the displacement of the spring after adjustment.

Hooke's law is an example of elasticity property of a material which is the ability of the object to return to a normal shape after experiencing a distortion also called "restoring force"
