Question

A projectile is projected with a kinetic energy E. 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 1

Answer:

Kinetic energy of a projectile is minimum at the highest point .So the horizontal distance is half of the range R i.e ,0.5R
