A solid rocket motor is designed with a cylindrical end-burning propellant grain of length $1 \mathrm{~m}$ and diameter $32 \mathrm{~cm}$. The density of the propellant grain is $1750 \mathrm{~kg} / \mathrm{m}^{3}$. The specific impulse of the motor is $190 \mathrm{~s}$ and the acceleration due to gravity is $9.8 \mathrm{~m} / \mathrm{s}^{2}$. If the propellant burns for a period of $150 \mathrm{~s}$, then the thrust $(\mathrm{in} N)$ produced by the rocket motor is_____________
