Katie was pulling a sled with her puppy in it. Katie's sister got into the sled with the puppy. How would the sled's speed most likely change after Katie's sister got into the sled?

• The speed would increase due to the change in mass

• The speed would decrease due to the change in mass

• The speed would increase due to the change in friction

• The speed would decrease due to the change in gravity

Ana is pushing a wheelbarrow of rocks. She stops and unloads half of the rocks. How will this effect the force needed to move the wheelbarrow?

• Gravity is increased, making the wheelbarrow easier to move

• Gravity is decreased, making the wheelbarrow harder to move

• Friction is increased, making the wheelbarrow harder to move

• Mass is decreased, making the wheelbarrow easier to move
