Answer:
answer 1 b
Step-by-step explanation:
answer 2 d
A and B I believe.
It would be A because jump height can be found out by the amount of force you exert to get you into the air minus the gravitational force.
It would also be B because the amount of time you run on the track can be found out by dividing the track length by your speed on the track.
