• The cart moves at the same speed.

• The cart speeds up.

How does the cart's direction change when it enters the grass at an angle?

• It stops moving.

• It continues straight.

• It turns towards the right.

• It turns towards the left.

• It speeds up and bends away from the normal.

• It speeds up and bends towards the normal.

When light enters a medium perpendicularly, what happens to its speed and direction?

• Speed decreases, direction stays the same.

• Speed increases, direction stays the same.

• Speed decreases, direction changes.
