Question

An unrestrained child is playing on the front seat of a car traveling in a residential neighborhood at 35 km/h. a small dog runs across the road and the driver applies the brakes, stopping the car and missing the dog. with what speed does the child strike the dashboard, presuming that the car stops before the child does so?

Answer 1

then break for speed = distance / time
                                  = 100 / 10
                                  = 10 m/s

it's in Km/hr is 10 x (18/5) = 18 x 2 = 36 Km / hr


i hope it will help you
