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 6 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...plz answer fast experts
