James asks…A car moving at 50 km/hr skids to a stop in 15 m with locked brakes..?A car moving at 50 km/hr skids to a stop in 15 m with locked brakes. How far will the same car moving at 150 km/hr take to skid to a stop with locked brakes?
is it 45 m?Nancy answers:Using an equation of motion
v^2 = u^2 + 2as
where v = 0, u = 50km/h (convert to m/s), s = 15m
By plugging in the values, you can find the retardation (negative acceleration) of the car.
Assuming acceleration remains the same,
