Question

In a projectile motion , the range of projectile is given by R= u^2sin2x/g. The value of x for which range becomes maximum is
A) 0
B) Π/2
C) Π/3
D) Π/4

Answer 1

Explanation:

differentiating R w.rt x & equating to 0, we get

cos2x = 0

2x = (π/2)

x = (π/4) for which range will be maximum
