MCQ
A projectile is fired with $KE$ of $1\,kJ$. If the range is maximum, .......... $J$ is its $KE$ at the highest point.
- A$250$
- ✓$500$
- C$750$
- DNone of these
✓
Answer
Correct option: B.
$500$
b
Angle of projection will be $45^o$. At the highest point, $KE$ is due to the horizontal component of velocity. It will be half of the initial $KE$ , i.e, $500\,J$ .
