A missile is launched with a speed of 75 ms-1 at an angle of 22° above the surface of a warship. Find the horizontal range achieved by the missile. Ignore the effects of air resistance.
[Take g = 10 ms-2]
195 m
271 m
391 m
136 m
Correct answer is C
U= 75 ms−1 =22º, g= 10 ms−2 , R=?
R= U2sin2θg
⇒R= 752×sin2(22)10
⇒R= 5625×Sin4410
⇒R= 5625×0.694710
⇒R= 3907.6910
⇒ 391m
