Collision of a Ball with a Cart
A cart filled with sand has a mass of m₁ = 100 kg and moves in a straight line on a horizontal surface at a constant velocity of v₁ = 1 m/s. Coming from the opposite direction, a ball of mass m₂ = 2 kg flies at v₂ = 70 m/s, strikes the cart, and embeds itself in the sand.
In which direction and at what speed will the cart move after the ball hits it? (Give a negative number if the velocity is in the direction of the ball.)
In which direction and at what speed will the cart move after the ball hits it? (Give a negative number if the velocity is in the direction of the ball.)
