You are two friends from our class with a physics problem where a cart is pushed up a ramp. in examining the motion of the cart up the ramp, one friend says that the acceleration has to be negative because the cart is slowing down. the other friend says the acceleration can be positive or negative, but it depends on the motion detector. what do you think and what would you say to your friends to convince them of your point of view
