Question

if a ball is tossed from ground level upward at a speed of 44 m/s how long will it take to reach its maximum height

Answer 1

H=V^2/(2*g)=44^2/(2*10)= 96.8
Not considering the air friction

Answer 2

@ellina so 96 seconds?

Answer 3

t=v/g=44/10=4.4s
in 4.4 seconds

Answer 4

@ellina what is that first equation for? sorry im confused

Answer 5

nevermind

Answer 6

@ellina where did you get 96.8 then 4.4 seconds

Answer 7

you are asking the max height
96.8 meter is the height

Answer 8

and it takes only 4.4 second to get that height

Answer 9

OK , I didn't read the problems seriously,sorry

Answer 10

@ellina the other part is .. how long will it take to return to ground level (the time for entire trip)

Answer 11

then ,you will use the max height to caculate the rest time
t=sqrt{2 times H div g}=sqrt{2times96.8div10}
