Question

6.
Three blocks m = 3 kg, m2 = 2 kg, m3 = 5 kg, lie on an inclined
frictionless surface as shown in the figure. (Take g = 10 m/s)
(a) What force (F) parallel to the incline is needed to push the
blocks up the plane with an acceleration a = 2 m/s??
(b) Find the contact force between m & m2 and m2 & m3. When the
blocks are moving up with an acceleration of 2 m/s? up the
inclined.​
