A cannon and a target are 5.1 km apart located on the same level. Find the time to hit the target. Speed of cannot is 240 ms -1 . Assume no air drag.
Text Solution
Verified by ExpertsThe correct answer is:
A
5.1 = u 2 sin2 θ θ /g
or sin 2 θ θ = 
= 
2 θ θ = 61 0 42' or θ θ = 30 0 51'
T = 
= 24.69 or T =
.
