Can someone me with these 2 questions
1) a car takes 76 metres to stop once a driver has noticed a hazard. if the thinking distance of the driver was 14m and the speed of the car was 8m/s. how long did it take the brakes to slow the car down to a stop?

2) a lorry travels 28m when stopping from a speed of 4m/s. if its braking distance was 18m, what was the driver's reaction time?

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.

that the claims meet official rules.

don't misinterpret the claims
