Reference no: EM13244344

A toy car with a mass of 120 g moves to the right with a speed of 0.62 m/s. A small child drops a 21.0-g piece of clay onto the car. The clay sticks to the car and the car continues to the right. What is the change in speed of the car? Consider the frictional force between the car and the ground to be negligible.
