Question

find the velocity of projection of missile which has a horizontal range of 150m, if the time of flight for that range is 3 seconds​

Answer 1

Answer:

horizontal range of 150m.

time is a flight for that range is 3 seconds.

We know that ,

time is a flight for that range is 3 seconds,

From eqⁿ 1 ,

225 × cos θ = 1500

cos θ = 1500 / 225 = 20/3

therefore , sin θ = 3 / √409
