What is the downward acceleration of a projectile that is released from a missile accelerating upward at g=9.8 m/s2
The downward acceleration of any object or projectile which is free falling is always 9.8 m/s2. This is acceleration due to gravity due to the gravitational pull of the earth.
Therefore the projectile will have a downward acceleration of 9.8 m/s2 or -9.8m/s2 if the downward direction is considered negative.

A uniform 7 kg rod with length 10 m has a frictionless pivot at one end. The rod is released from rest at an angle of 23 degrees beneath the horizontal.What is the angular acceleration of the rod immediately after it is released?The moment of inertia of a rod about the center of mass is 1/12 mL2 , where m is the mass of the rod and L is the length of the rod. The moment of inertia of a...
EXPLORE A projectile is launched with a launch angle of 30° with respect to the horizontal direction and with an initial speed of 40 m/s. (A) How do the vertical and horizontal components of the projectile's velocity vary with time? (B) How long does it remain in flight? (C) For a given launch speed, what launch angle produces the longest time of flight? CONCEPTUALIZE Consider the projectile to be a point mass that starts with an initial velocity, upward and...
A 96.5-kg person stands on a scale in an elevator. What is the apparent weight when the elevator is (a) accelerating upward with an acceleration of 1.57 m/s2, (b) moving upward at a constant speed, and (c) accelerating downward with an acceleration of 1.79 m/s2?

2) A projectile is launched into the air from ground level heading east. The projectile is launched at an angle of 45° with an initial velocity of 20 m/s. The wind is blowing the projectile in the north direction, with an acceleration of 2 m/s2. Assuming gravity is pulling the projectile downward toward the ground at a constant 9.8m/s², where does the projectile land in relation to its starting position?
