Question 268 of 308

The maximum range of a bullet fired from a toy pistol mounted on a car at rest is $R_0=40 \mathrm{~m}$. What will be the acute angle of inclination of the pistol for maximum range when the car is moving in the
direction of firing with uniform velocity $\mathrm{v}=20 \mathrm{~m} / \mathrm{s}$ on a horizontal surface? $\left(\mathrm{g}=10 \mathrm{~m} / \mathrm{s}^2\right)$
