A 10.0-kg cannonball is dropped from a tall bridge into a river. The diameter of the cannonball is 20.0 cm, and the aerodynamic constant for the ball is C = 0.100. Assuming that the acceleration of gravity is 10.0 m/s²and that the density of air is 1.30 kg/m³, the terminal velocity of the cannonball is A) 110 m/s. B) 165 m/s. C) 221 m/s. D) 275 m/s.

The terminal velocity can be calculated using the formula: $ v_t = \sqrt{\frac{2mg}{\rho C_d A}} $. Here, m = 10 kg, g = 10 m/s², ρ = 1.3 kg/m³, C_d = 0.1, and A = π(0.1)² m². Plugging in these values gives approximately 221 m/s.
