Question

A stone falls from a balloon that is descending at a uniform rate of 12 m/s. The displacement of the stone from the point of release after 10 s is (A) 490 m (B) 510 m (C) 610 m (D) 725 m

Tardigrade Admin · Accepted Answer

u=12 m / s , g =9.8 m / s 2, t=10 s Displacement =u t+(1/2) g t2 =12 × 10+(1/2) × 9.8 × 100=610 m .

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

490 m

510 m

610 m

725 m

$u = 12 m / s, g = 9.8 m / s^{2}, t = 10 s$
Displacement $= u t + \frac{1}{2} g t^{2}$
$= 12 \times 10 + \frac{1}{2} \times 9.8 \times 100 = 610 m .$
