A box of mass 1.25k is subjected to 2 forces F1=1.5i+3j and F2=1i-1.75j. (1) Find the acceleration of the box. (2) If the box has an initial velocity=1.50(m/s)i at the origin find the position and velocity of the box at t=2s.

A box starts from rest and slides down a 45degree incline. The distance from the box to the bottom of the incline is 2.5m. The kinertic frictional coefficient between the box and the incline is .25.

(1) Find the acceleration of the box.

(2) Find the speed of the box at the bottom of the incline (3) Time it takes for the box to reach the bottom.

3 blocks are stacked against each other on a horizontal surface. A Horizontal force=50N is applied to the first box (Mass1=4kg, Mass2=2.5kg,Mass3=2kg). Find the acceleration of the blocks and the contact force between the boxes (Neglect friction)
