Question

If a projectile is projected at an angle of 30
while providing it with an initial velocity of
100m/sec, the maximum height reached by it
in meters is
a)110m
b)125m
c)140m
d)155m​

Answer 1

Answer:

answer of this question is option d

Answer 2

Answer:

127.55 m

Explanation:

angle = 30

initial velocity = 100m/s

final velocity ( v ) at maximum height = 0

Direct apply the formula.

maximum height = u*u*sin^2angle given / 2*g

g = 9.8

maximum height = 100*100*1/2*1/2 / 2*9.8

Maximum height = 127.55 m
