#### Explanation:

Refer to the figure below

As the mass slides down the inclined plane, we see that Normal reaction

As there is movement in sliding down there is net force given as

Using Newton's second law this net force can be written as

#F_"net"=ma# .......(1)

Where#m# is mass#and a# is acceleration produced.

Using the kinematic equation

Solving for

Inserting value of
