Question

. A bus moving with speed of 20m/s. Suddenly brakes are applied so as to produce uniform acceleration of -1m/s2 . find how far the bus will go before it is bought to rest.

Answer 1

Answer:

100 m

Step-by-step explanation:

u = 20 m/s

v = 0

Deceleration (a) = -1m/s²

s = ?

v²-u² = 2as

= 0 - (20)²= 2 (-1) (s)

= -400 = -2s

= s = -400/-2 = 100 m

Therefore distance is 100 m
