Trucks

Jeremy has two toy trucks. His red truck has a higher mass than his blue truck. What will he have to do to make the two trucks go the same speed?

• He can push both trucks with the same force for the same period of time.

• He can push both trucks with the same force, but he will have to push the red truck for a longer time.

• He can push both trucks for the same amount of time, but he will have to push the red truck with more force.

• He can push both trucks for the same amount of time, but he will have to push the blue truck with more force.
