A car's engine has a power of 80 kW. What is the force exerted by the engine when the car is moving at a velocity of 32 m/s? (A) 1.50 x 103 N (B) 2.50 x 103 N (C) 3.00 x 103 N (D) 3.50 x 103 N

The power of the engine is $P = 80 \text{ kW}$.
The velocity of the car is $v = 32 \text{ m/s}$.
The relationship between power ($P$), force ($F$), and velocity ($v$) is given by:

$$P = F \cdot v$$

$$F = \frac{80000 \text{ W}}{32 \text{ m/s}}$$ $$F = 2500 \text{ N}$$

$$F = 2.50 \times 10^3 \text{ N}$$

This matches option B.

The final answer is \boxed{\text{2.50 \times 10^3 N}}.
