Sand is falling on a flat car being pulled with constant speed. The rate of mass falling on the cart is constant. Then the horizontal component of force exerted by the falling sand on the cart (sand particles sticks to the cart)

A mass m1 with initial speed v0 in the positive x - direction collides with a mass m2 = 2 m1 which is initially at rest at the origin as shown in figure. After the collision m1 mooves off with speed v1 = v0 /2 in the negative y - direction and m2 moves off with speed v2 at angle theta.
