Question

Two blocks a and b are connected to each other .the string and the spring are massless and pulley is frictionless. block B slides over thehorizontal top surface of stationery block C and block A slides along thevertical side of C both with same uniform speed. the coefficient of friction between the blocks is 0.2 and the spring constant of the spring is 1960 N/m. If mass of block A is 2Kg calculate 1. Mass of block B 2. energy stored in spring?

Answer 1

The exact solution is not known to be as well. However, you have to use the formula: U = ½ kx^2

Here you will be able to obtain the value of U which will guide you to actual Force of the spring that is given.

Then, you will able to obtain the total energy.
