A blоck with а mаss оf M kg is sliding dоwn а rough inclined plane that makes an angle of θ° with the horizontal. The friction force (f) acting on the block opposite to the motion as shown in figure. Resolving weight in rectangular componenets. The formula value of "W" will be [1] N. The Normal reaction force , means forula value for "Z" will be [2] N. The formula value of "X" will be [3], and The formula value of "Y" will be [4]. The net force Fnet will be [5]. The acceleration of the block as it slides down the incline wil be [6] m/s2. (Hint: Solve by drawing its free body diagram in your notebook).
