## Question

###### Imagine a cart with an open top that moves without any loss ofspeed due to friction. Suppose that you begin to gently pour waterinto the cart so that you do not affect its overall momentum. Whatchange do you expect to see in the motion of the cart? Support youranswer by considering the equation for momentum and reasoning aboutwhat happens as the mass gets bigger when amount of momentum isconstant.
