Question

4) A bus is moving with a velocity 36km/h. It travellers with a uniform acceleration of 2m/sec². What will be its velocity after 10 sec? ​

Answer 1

Given :-

A bus is moving with a velocity 36km/h. It travellers with a uniform acceleration of 2m/sec²

To Find :-

What will be its velocity after 10 sec? ​

Solution :-

We know that

1 km/h = 5/18 m/s

36 km/h = 36 × 5/18 = 10 m/s

Now, By using 1st equation of motion

v = u + at

v = 10 + 2(10)

v = 10 + 20

v = 30 m/s

Therefore

Velocity after 10 sec is 30 m/s

Answer 2

plz mark as brainliest

Solution :-

We know that

1 km/h = 5/18 m/s

36 km/h = 36 × 5/18 = 10 m/s

Now, By using 1st equation of motion

v = u + at

v = 10 + 2(10)

v = 10 + 20

v = 30 m/s

Therefore

Velocity after 10 sec is 30 m/s ​
