A stone propelled from a catapult with a speed of 50m/s attains a height of 100m.Calculate:(a)the time of flight?

time of fligt

t=2*√2H/g
=2*√2*100/10
=2*√200/10
=2*√20
=2*4.47
=8.94s

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

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)

= 50²*sin(2*63.4⁰)/10
=2500*sin(126.8⁰)/10
=250*0.8007
=200.2m
R≈200m

T=8.945

Which Formular Will You Use To Get The Angle Of Projection?

A STONE IS PROPELLED FROM A CATAPULT WITH A SPEED OF 500MS ATTAINS THE HEIGHT OF 100M.CALCULATE,a:THE TIME OF FLIGHT,b:THE ANGLE OF PROJECTION,c:THE RANGE ATTAINED.

Tether=sin-1(Tg/2u)

am asking question a stone propelled from a catapult with a speed of 50 m/s attains a height of 100m calculate (a)the range attained

I THINK ANONYMOUS MAY BE CORRECT

I don't get why it is multiplied by 2

how are we going to calculate the angle of projection and the range attained

Thanks so much for solving this problem already, i appreciate u very much

Anonymous are right

How did you get the tita

Exactly how did you get the theta

pls how did u solve the angle of projection

Thanks so much i appreciate

A stone propeller from a catopon often a gift of 100m calculate

What is the formula used in time of flight

Thank you very well

thanks

A how do i calculate a stone propelled from a catapult with a speed of 50ms attains a height of 100m.calcute the time of flight

(a)the angle of projection (b) the range attained

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
