Question

Which equation would best help solve the following problem?



Petra throws a ball up with an initial vertical velocity of 35 ft/s from a platform that is at ground level. How long will the ball be in the air?





A.


16t2 + 35t = 0


B.


–4.9t2 – 35t = 0


C.


–16t2 – 35t = 0


D.


–16t2+ 35t = 0

Answer 1

Answer 2

deeezzz nuts loool

Answer 3

loool

Answer 4

h=−16t2+vi+h0
vi initial velocity
h0 initial height

Answer 5

D

Answer 6

16t2 + 35t = 0

Answer 7

so your saying its A?

Answer 9

take another look at Deez's answer

Answer 10

its D

Answer 11

Deeezz nutsss

Answer 12

Got em2

Answer 13

YEEES

Answer 14

use one of the equations for constant acceleration
s = 0 , u = 35 , a = -32, t = time
s = ut + 0.5at^2

0 = 35t - 0.5*32t^2
35t - 16t^2 = 0

Answer 15

D

Answer 16

s = displacement , u = initial velocity, a = acceleration due to gravity , t = time
