A speeding car is pulling away from a police car. The police car is moving at 30 m/s. The radar gun in the police car emits an e

Gekata [30.6K]

Answer:

65.625 m/s

Explanation:

$F=20\times 10^9 Hz$

$\Delta F=F_r-F_t=4750 Hz$

c = Speed of light = 3×10⁸ m/s

Relative speed

$v=\frac{\Delta F}{2F}\times c\\\Rightarrow v=\frac{4750}{2\times 20\times 10^9}\times 3\times 10^8\\\Rightarrow v=35.625\ m/s$

Relative speed = 35.625 m/s

Velocity of speeder = Velocity of police car + Relative speed

⇒Velocity of speeder = 30 + 35.625 = 65.625 m/s

∴ Velocity of speeder is 65.625 m/s
