Question

A baseball player hits a ball. The ball leaves the bat with an initial upward velocity of 35 meters per second. If the ball is 1 meter off the ground when it leaves the bat, about how many seconds will it take for the ball to hit the ground?

Answer 1

i hate these

Answer 2

speed = distance over time.

Answer 3

thats nt the answer

Answer 4

ah now we have a problem!

Answer 5

hmm

Answer 6

was it hit vertically up in the air?

Answer 7

do you know what formula to use?

Answer 8

7 seconds -0.03 seconds
14.34 seconds 35.133 seconds

Answer 9

its one of those

Answer 10

0.03

(not in nedative)

Answer 11

(negative)

Answer 12

uhh negatie is the only one

Answer 13

you have to use the formula for free fall

Answer 14

wtf idk how thats why im asking u guys lol

Answer 15

do you have an example for another problem with a solution?

Answer 16

no

Answer 17

i know it in feet. myininaya knows it in meters

Answer 18

i think it is
\[-4.9t^2\] yes?

Answer 19

in meters that is. so you have to solve
\[1+35t-4.9t^2=0\] for t. lets see mr khan do that in two seconds

Answer 20

in any case i think you get 7

Answer 21

finally i got one!

Answer 22

.3s

Answer 23

Vy= dy/ t . solve for t.. t= dy/Vy, amnd thus 1/35, seconds cancel out, .3m

Answer 24

wouldn't you need to know the initial upward acceleration of the ball at the moment it left the bat?

Answer 25

let me get my physics referance table, is 1m its max height
