Question

a bus travelling at 50km/hr is brought to rest with uniform retadation in 30s find retardation

Answer 1

here is your naswer .. :-

answer :-

bus speed = 50km/hr

uniform retadation = 30 s

solve :- ( v - u) ÷ t

= 0 - 13.88 ÷ 30

= - 0.46

answer is here = - 0.46

for more trustful answer follow me.

hope this helps you......

Answer 2

The retardation is - 0.46 m/s²

Given:

Speed of bus = 50km/hr

Retardation of bus = 30s

To find:

The retardation

Solution:

Since the speed of the bus is 50km/hr

Initial velocity will be -

= 50 × 5/18

= 2500/18

= 13.88

Now, uniform retardation = 30 s

Using the formula -

Acceleration

= ( v - u)/ t

= 0 - 13.88/ 30

= - 0.46

Answer: The retardation is - 0.46 m/s²
