A projectile is projected with a kinetic energy K. Its range is R. It will have the minimum kinetic energy, after covering a horizontal distance equal to
A
0.25 R
B
0.5 R
C
0.75 R
D
R
Answer
0.5 R
Explanation
Solution
Projectile possess minimum kinetic energy at the highest point of the trajectory i.e. at a horizontal distance R/2.
