Question

A stone falls from a balloon that is descending at a uniform rate of 12 m/s. The magnitude of the displacement of the stone from the point of release after 10 sec is

Options:

A . 490 m

B . 510 m

C . 610 m

D . 725 m

Answer: Option C
:
C
u = -12m/s, g = - 9.8 m/

s e c^{2}

, t = 10sec
Displacement =

u t + \frac{1}{2} g t^{2}

- 12 \times 10 + \frac{1}{2} \times - 9.8 \times 100 = - 610 m

(since downwards)
The magnitudeis 610m.
