Question

The acceleration one projectile relative to another projectile is

• A. -g
• B. g
• C. 2g
• D. zero

Answer 1

Answer: (D)

zero

Answer 2

The acceleration of a projectile relative to another projectile is zero Both the particles will have same magnitude of acceleration in the same direction The magnitude of the acceleration of the projectiles will be $-g$ (towards the earth) The relative acceleration between the projectiles will be $\begin{array}{l} a_{12}=-g-(-g) \\\ a_{12}=0 \end{array}$ So the relative acceleration between the particles is zero
