Question: A projectile is thrown with an initial velocity of \((v_{x}^{\widehat{i}} + v_{y}^{\widehat{j}})\) m...
A projectile is thrown with an initial velocity of (vxi+vyj) m s–1 . If the range of the projectile is double the maximum height, then vy =
A
vx
B
2vx
C
3vx
D
4vx
Answer
2vx
Explanation
Solution
tan q = vxvy …..(1)
R = 2 H
tan q = 2 …...(2)
vxvy = 2 ̃ vy = 2vx
