Question

a person pushes a stone of 10 ^10 kg mass by applying a force of only 10 N for just 4sec work done will be ​

Answer 1

Answer:

The answer will be zero

Explanation:

Force wont be enough to move the stone , no displacement leads to 0 work done

Answer 2

Answer:

8×10^-8 Joules

Explanation:

F = ma

10 = 10^10a

a=10^-9 m/sec²

S=ut+1/2at²

S=1/2×10^-9×16

S=8×10^-9 metres

Work = Force×Distance

W = 10×8×10^-9

W=8×10^-8 Joules
