MCQ
A girl weighing $50\ kg$ makes a high jump of $1.2m.$ What is her kinetic energy at the highest point? $(g = 10\ ms^{-2}$)
- A$6000J$
- B$600J$
- C$60J$
- ✓Zero
✓
Answer
Correct option: D.
Zero
mass of girl $M = 50\ kg$
$h = 1. 2m$
A girl is jumping vertically upward, when it will reach at maximum Hight its velocity will become zero
i.e $in_f\ K.$
And $=\frac{1}{2}\text{min}^2=\frac{1}{2}\text{m}\times0=0$
$h = 1. 2m$
