A car moving at 44 km / h skids 16 m with locked brakes. How far will the car skid with locked brakes at 110km / h

100 m

Explanation:

44 km/h = 12.2 m/s

110 km/h = 30.6 m/s

Given:

Δx = 16 m

v₀ = 12.2 m/s

v = 0 m/s

Find: a

v² = v₀² + 2aΔx

(0 m/s) ² = (12.2 m/s) ² + 2a (16 m)

a = - 4.67 m/s²

Given:

v₀ = 30.6 m/s

v = 0 m/s

a = - 4.67 m/s²

Find: Δx

v² = v₀² + 2aΔx

(0 m/s) ² = (30.6 m/s) ² + 2 (-4.67 m/s²) Δx

Δx = 100 m
