2D Motion Entrance Ticket

​Consider the following photo...

​There is a little yellow ball that can be launched straight up relative to the red Pasco cart (which should look familiar!).

Multiple Choice

If the cart is moving along the track at a constant speed, where is the ball going to land if it is launched straight up?

• infront of the cart

• in the cart

• behind the cart

Multiple Choice

Why does the ball land back in the cart?

• Because the x- and y- axes of motion depend on each other.

• Because the x- and y- axes of motion are independent of each other.

• The ball was attached to the cart by a thin elastic cord that pulled it back down.

• None of the above.
