Answer

vol of prism = area of base * height height of prism = 1 m base consist 1 rectangle (sides are 1 and √3) and two triangles ( base = √3 and height 1/2 ) area of base = (1*√3) + 2*(1/2*√3*1/2) = √3 + √3/2 = 1.5√3 ans

Answer

Answer

horizontal range = ( u^2 sin2a )/ g = 3 and a = 30 degree so we get u^2/g = 2√3 and max. range can be achieve by shoot at 45 degree so max. range = u^2/g = 2√3 = 3.464 m therefore hit the target 5 km away is not possible.

Answer

tan 30 = distance traveled by plane in 10 s / height at which plane is flying (3400 m) distance = 3400/√3 = 1962.99 m speed = d/t = 196.299 m/s ans.
