• She is not moving

• She is moving 2 km per hour

• She is moving 4 km per hour

• She is moving 54 km per hour

A passenger walks 4 km per hour toward the front of a train that is moving 50 km per hour. What is her motion relative to someone standing next to the tracks as the train passes by.

• She is not moving

• She is moving 4 km per hour

• She is moving 50 km per hour

Four identical tennis balls are dropped at the same time and from the same height. Ball 4 lands first. Why?

• the parachute is bigger, producing more drag.

• the parachute is smaller, producing less drag.

• the parachute is circular, producing more drag.

• the parachute is a rectangle, producing less drag.
