Question

A projectile is fired with a velocity of 100.3 m/sec. at an elevation of 60&#176;. The velocity attained by the projectile when it is moving at a height of 100 m, is-A-80 m/sec.B-85 m/sec.C-75 m/sec.D-90 m/sec.E-70 m/sec.-E-90 m/sec.

APTITUDE CRACK · Accepted Answer

The correct option is  E 90 m/sec. The velocity of a projectile a height h is given by: v = sqrt(u^2 2gh). v = sqrt(100.3^2 2*9.81*100). v = 90 m/sec.
