Question

A bus starts from rest and attains a speed of 36 km/hr in 10 minutes while moving with uniform acceleration .Calculate the acceleration. please answer fast : )

Answer 1

A/q Initial speed = u = 0

Final speed = v = 36 km/h

Time = t = 10 min = 1/6h

Let acceleration = a As per the 1st law of motion, v=u + at 36 = 0 + a/6  a = 36 x 6

a = 216 km/h2

Answer 2

Answer:

The acceleration of the bus is 216 km/hr²

Step-by-step explanation:

Given,

A body is starting from rest, that is , its intial velocity will be 0

u = 0

Then it is given that it attains a speed of 36km/hr in 10 minutes

v = 36 kmph

t = 10 min

We know ,

1 minute = 1/60 hr

10 minutes = 10 /60 = 1/6 hr hr

We need to find the acceleration

We know using 1st equation of motion, that is,

v = u + at

Substituting the values,

36 = 0 + a * 1/6

a = 36 * 6

a = 216 km/hr²

Hence,

The acceleration of the bus is 216 km/hr²
