Question

A 1.00kg box sits on a 4.00kg block which rests on a smooth table. A force of 12N acts on an angle of 25 degrees to the horizontal on block M1 and causes both blocks to move with the same acceleration.

1) find the acceleration of each block (2.18 m/s^2 in x direction)
2) the normal force exerted by table on M1 (54.1N in y direction)
3) the frictional force between the two blocks (-2.18 N in x direction for M1 and 2.18N in x direction for M2)
