A rocket lifts off from the ground and accelerates upwards at . seconds after liftoff a piece breaks off from the bottom of the rocket. After breaking off, how much time it takes approximately to reach the ground? (Take )
- A
- B
- C
- D
Answer & Solution
Correct Answer
(D)
Step-by-step Solution
Detailed explanation
The distance covered by rocket after 20 s, h1=12at2=12×1×202=200 m and, the velocity of the brake piece from the rocket is, v=0+at=20 m s-1, it means the addition distance covered by piece in the upward direction is,…
