A toy car was used in an investigation about forces. During which of the following scenarios was the car experiencing balanced forces?

• The toy car speeds up as it rolls down a ramp.

• The toy car travels forward at a constant speed.

• The toy car slows down as it rolls up a hill.

• The toy car changes direction at a constant speed.

The diagram below shows a skateboarder pushing himself forward with a force of 25 N while the wind pushes back with a force of 5 N. How will the skateboarder be affected if the force of the wind increases to 8 N?

• The speed of the skateboarder will increase.

• The speed of the skateboarder will decrease.

• The speed of the skateboarder will remain constant.

• The skateboarder will come to a stop.
