Physics Midterm concept review

Scott drives a Jeep 12 km east, then 4 km north, then finally 3 km west. He traveled a total distance of:

• 5 km
• 10 km
• 13 km
• 19 km

A ping-pong ball rolls forward 6 meters, and bounces backward 3 meters. It traveled a total distance of:

• 9 meters
• 6 meters
• 3 meters
• 0 meters

During a game of dodgeball, Marina runs 2.45 meters forward to grab a dodgeball, then runs 1.25 meters backward to avoid a opponent's dodgeball. Her displacement would be:

• 3.7 meters backwards
• 1.2 meters backwards
• 3.7 meters forwards
• 1.2 meters forwards

• 36 feet

• 24 feet

• 0 feet

• 12 feet
