A mass of 60 kg slides on a table. The frictional force is 60 times the velocity and the mass is

being pushed with a force of 54 sin 2t N. Find the velocity as a function of time if v = 0 at

t = 0.

Dear Swapnil,

F= m*a and  a= dv/dt .............

Using these two relations we can write,

accelaration of mass , = F/m - 60* integration(a)wrt time

differentiating both sides to get the expression for velocity.

Best Of luck
