Question

A ball is released from a hot air balloon moving downward with a velocity of
-10.0 meters/second and a height of 1,000 meters. How long did it take the ball to reach the surface of Earth? Given: g = -9.8 meters/second2.

Answer 1

what formula do i use for this equation

Answer 2

h - ho =1/2g(t-to)^2 + vo(t-to)

Answer 3

what

Answer 4

find t? from equation above

Answer 5

how

Answer 6

when to = 0,ho=1000m, vo=-10m/s

Answer 7

S=ut+(1/2)gt^2

Answer 8

1000=(-10)(9.8)+(1/2)(9.8)(t^2)
t=14.97s

Answer 9

ok so how would i work that

Answer 10

look direction

Answer 11

-1000= - + (-)

Answer 12

confusing

Answer 13

g and v the same direction

Answer 14

-1000=-1/2gt^2 _ 10t
