```							Dear student The coefficient of friction = 0.25. The magnitude of acceleration =?It is quite interesting that force has a value, only when the force applied on the body tends to move with acceleration which means velocity must keeps on increasing.Force = Mass x Acceleration. Acceleration = force/mass. On substituting the values, we get 75 – 0.25/1 = 72.5 ms^-2.
