Dynamics of a solid body

Problem 1.261

A plank of mass \(m_{1}\) with a uniform sphere of mass \(m_{2}\) placed on it rests on a smooth horizontal plane. A constant horizontal force \(F\) is applied to the plank. With what accelerations will the plank and the centre of the sphere move provided there is no sliding between the plank and the sphere?

Reveal Answer
w1=F/(m1+2/7m2);w2=2/7w1w_{1}=F /\left(m_{1}+2 /_{7} m_{2}\right) ; w_{2}=2 / 7 w_{1}
