A car's braking distance is the distance it travels while in the process of braking after initially traveling at a certain speed. Suppose a car can brake at -8.3 m/s². (a) Suppose the car is initially traveling at 15.0 m/s (about 34 mph). How much time does it take to stop?

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
