Question

When the front a 5 m long bus traveling at constant speed of 20 m/s is 55 m away from an intersection, the traffic light turns red. the driver's reaction time is 0.25 s. the bus can accelerate up to 2 m/s or slows down at a maximum rate of 4.3 m/s. the intersection is 22 m wide. should the driver step on the brakes or on the gas pedal?

Answer 1

Of course the driver should not step on the gas pedal because the light has already turned red.

It would make sense if you said the traffic light turned yellow and said how many seconds later the yellow would turn red
