An arrow is shot vertically upward at a rate of 160 feet per second from ground level. Use the projectile formula h

to determine when the arrow hit the ground.

after 10 seconds

Step-by-step explanation:

h=-16t^2+v0*t+h0

ground level is h0 with a measure of 0

160 is v or velocity

0=-16t^(2)+160t+0

0=-16t^(2)+160t

0=16t(-t+10)

0/16t=(-t+10)

0=-t+10

-10=-t

10=t

t=10

step-by-step explanation:

answer: all of the odd numbers were opened

the first person was the one that was opening all of the lockers. since one is odd, this causes all of the odd number lockers to be opened in the end.
