A stone propelled from a catapult with a speed of 50m/s attains a height of 100m.Calculate:(a)the time of flight?
Answered by Damon
Just as long as anything else that goes up 100 meters and falls

Which is twice as long as it takes to fall 100 meters

h = (1/2) g t^2
100 = 4.9 t^2
t = 4.52 seconds to fall
so about 9 seconds
Answered by Sabuda
time of fligt
t=2*√2H/g
=2*√2*100/10
=2*√200/10
=2*√20
=2*4.47
=8.94s

T=8.945
Answered by Angelo
I don't get why it is multiplied by 2
Answered by Aderinola
how are we going to calculate the angle of projection and the range attained

A. time of flight
t=2*√2H/g
=2*√2*100/10
=2*√200/10
=2*√20
=2*4.47
=8.94s
B. The angle of projection
sinø=0.8944
Ø= sin–¹(0.8944)
Ø=63.4314654⁰
Ø ≈ 63.43⁰

C. Range
R=u²sin2ø/g
R=? u=50 , ø=63.4⁰, g= 10
= 50²*sin(2*63.4⁰)/10
=2500*sin(126.8⁰)/10
=250*0.8007
=200.2m
R≈200m
