A bus moving along a straight highway with speed of 72 ~km / h is brought to halt within 4 s after applying the brakes. The distance travelled by the bus during this time (Assume the retardation is uniform) is _____m.

Correct answer

0

Step-by-step solution

aligned & Initial velocity =u=72 ~km / h =20 ~m / s & v = u + at & 0=20+ a 4 & a =-5 ~m / s ^2 & v ^2- u ^2=2 as & 0^2-20^2=2(-5) . s & s =40 ~m aligned
