Question

A body Is projected at time t =0 from a certain point on a planet's surface with a certain velocity at a certain angle With the planet's surface assumed horizontal. The horizontal and vertical displacements x and y in meter respectively very with time t in second as x = 10√3t and y = 10t - t2 The maximum height attained by the body is. (A) 200 m (B) 100 m (C) 50 m (D) 25 m

Conparing standard equations u sin θ = 10, (1/2) g = I , H = (u2 sin2 θ/2g)

200 m

100 m

50 m

25 m

Conparing standard equations u sin θ = 10, 21​g = I , H = 2gu2sin2θ​

Conparing standard equations
$u$ sin $θ$ = 10, $\frac{1}{2} g$ = I , H = $\frac{u ^{2} s i n ^{2} θ}{2 g}$
