As a rocket is accelerating vertically upward at 92 m/s^2 near the Earth\'s surf

Question

As a rocket is accelerating vertically upward at 92 m/s^2 near the Earth's surface, it releases a projectile. Immediately after release the acceleration (in m/s^2) of the projectile is: A) 9.8 down. B) 9.8 up C) 9.2 down D) 92 up E) none of the above The motion a particle described in the velocity versus time graph shown in the figure. We can of is 6- say that its speed: A) increases. B) decreases and then increases. C) decreases. D) increases and then decreases. E) none of the above. A pilot drops a package from a plane flying horizontally at a constant speed. Neglecting air resistance, when the package hits the ground the horizontal location of the plane will A) be behind the package. B) be in front of the package. C) be over the package. D) depend of the speed of the plane when the package was released. E) none of the above. A satellite orbits the earth a distance of21.35 times 10^6 m above the planet's surface and takes 5.65 hours for each revolution about the earth. The acceleration of this satellite is closest to A) 1.11 m/s^2. B) 0.870 m/s^2. C) 3.01 m/s^2. D) 2.04 m/s^2. E) 1.47 m/s^2.

Explanation / Answer

(5) Answer:

Given the rocket is vertically upward at 9.2 m/S^2 and releases a projectile.

Once it releases projectile, the rocket come to rest and starts coming back via free falling due to Earth’s gravitation with an acceleration due to gravity which is 9.8 m/s^2.

So tha answer is 9.8 m/s^2 down - Ans (A)
