A moving cart of mass 3.5 kg crashes into a stationary cart of mass 10.5 kg as shown. The carts are prevented from touching one another during the collision by a pair of neodymium magnets mounted on the ends of the carts and positioned for repulsion. After separating, the more massive cart moves to the right at 1.4 m/s. What are the final speed and direction of motion of the less massive cart? strong magnets VFi VGi = 0 3.5 kg 10.5 kg Frictionless surface
