Question

The bus reaches velocity $v = 0.05 	imes 400 = 20 \, m/s$ when the brakes are applied and stops in 28 s. The braking distance and the fate of the cow (300 m ahead) are —

Accepted Answer

braking distance $\approx 280 \, m$; the cow is saved

Answer

braking distance $\approx 560 \, m$; the cow is hit

Answer

braking distance $\approx 300 \, m$ exactly; uncertain

Answer

braking distance $\approx 140 \, m$; the cow is saved

The bus reaches velocity v=0.05×400=20 m/sv = 0.05 \times 400 = 20 \, m/sv=0.05×400=20m/s when the brakes are applied and stops in 28 s. The braking distance and the fate of the cow (300 m ahead) are —
