A=-10 or 10 NOT 9.81

Question

1: A devout halloweener not only dressed as an astronaut, but travelled to the moon for the

full experience. The astronaut jumps on the moon with an initial upward velocity of 2.3m/s.

(our class average for the Jump mini Lab) If the acceleration of gravity on the moon is

-1.62m/s2, what is the highest the astronaut jumps? What is the hang time?

2: The DeLorean just had some repairs and is out for a test drive. It accelerates uniformly at

1.5 m/s² from rest to 39m/s. Immediately upon reaching 39m/s (before time travel which

occurs at 88mph), the brakes are applied, and it stops 2.5 s later. Find the total distance

traveled.

Answer 1

Hello Dessie,

Hope my explanation is easy to understand. My apologies for the few times I misspoke (At the end of the video I said "The total time" went I meant to say "The total Distance"). If you have any questions related to any of the steps that go into solving these two problems just let me know, and I'll reply back as soon as I can.
