Final answer:
The car will skid approximately 36 m with locked brakes at 150 km/h.
Step-by-step explanation:
When a car skids, it undergoes a deceleration due to the friction between the tires and the road. The distance a car skids depends on its initial speed and the coefficient of kinetic friction.
In this case, the car skidded 12 m at a speed of 50 km/h.
To find the distance the car will skid at 150 km/h, we can set up a proportion:
50 km/h / 12 m = 150 km/h / x
Cross multiplying, we get:
50 km/h * x = 150 km/h * 12 m
Simplifying, we find that the car will skid approximately 36 m with locked brakes at 150 km/h.
