Question

a bus retards uniform at a rate of 3 m/s2 and stops in 10 sec. with what velocity was the bus travelling

Answer 1

Answer:

Let acceleration of bus =-3m per s

Let final velocity (v) =0

Time taken =10 s

Using first equation of motion

V =U+AT

0=u +-3*10

0=u-30

-u=-30

u =30m per s

Answer 2

Explanation:

QUESTION:

A bus retards uniform at a rate of 3 m/s2 and stops in 10 sec. with what velocity was the bus travelling.

ANSWER:

Retardation or Acceleration (a) = $3m {s}^{ - 2}$

Time = 10s

So, velocity $= \frac{acceleration}{time} \\ = \frac{3}{10} m {s}^{ - 2} \\ = 0.3m {s}^{ - 2}$
