Question

The brakes applied to a car produce an acceleration of 10m/s^2 in the opposite direction to the motion. If it takes 5 seconds to stop after the application of brakes, then how much distance is covered by the car before coming to rest?

Answer 1

hey friend!!!!!

=>Acceleration = a = 10m/s2

=>Time = t = 5s

=> final velocity = 0m/s

let's initial velocity be "u"

let distance be "s"

we know that :

v = u+at

so

0 = u + (-10)(5)

u = 50m/s__________(1)

now

=> S = ut + 1/2(at2)
=> S = 50×5 + 1/2(-10)(25)
=> S = 250 -125
=> S = 125

thus distance travelled is "125m"

hope it will help you..
