A worker climbs a ladder and does 8 J of work on a 2 N object. What is the distance they lift the object?

• 18 m

• 4 m

• 10 m

• 6 m

Two factors that determine work are

• size of the force, and distance

• size of the force, and type of force

• mass, and distance

Fred kicks a ball with a force of 20N to George, who is 5M away. How much work was done to the ball?

• 25J

• 100J

• 4J

• 75J
