Question

Please answer this science question of work and energy chapter 5 th question

Answer 1

Answer:

At 10 m

$pe = mgh = 10 \times 10 \times 10 = 1000 \: j$

$ke = 0$

$me = pe + ke = 1000 + 0 = 1000j$

Mechanical energy will be conserved . So it will be same at all heights .

Use mgh formula for k.e. for each height h .

For p.e. use total /mechanical energy - p.e.
