Answer:
The correct answers are A and B.
Step-by-step explanation:
Zack has the following supplies available:
a friend with a bike
a bike ramp one meter tall and two meters long
a bike ramp two meters tall and two meters long
a tire pump with an air pressure gauge
a meterstick
Using only these supplies, Zack can investigate the following two questions:
A. Does a rider travel farther off a bike ramp if the bike tires are inflated to a higher air pressure?
Zack can investigate this question by inflating the bike tires to different air pressures and then having his friend ride off the two ramps. He can measure how far the rider travels off each ramp and compare the results.
B. Does the height of a bike ramp affect how far a rider can travel off of it?
Zack can investigate this question by having his friend ride off the two ramps, which are different heights. He can measure how far the rider travels off each ramp and compare the results.
Therefore, the correct answers are A and B.
