Question

A projectile launched upwards from ground has a range of 180m and its timeof flight is 10 s.The velocity(in m/s) after start is (angle of projection with horizontal is theta)?

Answer 1

@heena help

Answer 2

shakir wat u dont understand in this tell me

Answer 3

theta is not give so fow can we find the velocity??

Answer 4

hmm ok den first tell me the formula of flight and range?

Answer 5

r=u^2sin2theta/g T=2usintheta/g @heena

Answer 6

@Kryten

Answer 7

ok now u have time of flight so u can find 2usintheta then put the value of using theta in R formula

Answer 8

ok let me try

Answer 9

k i m here and show me ur work too if u till dont get the ans

Answer 10

yw :)

Answer 11

@heena after solving i got a wrong answer will u help
