Question

A bus increases its speed from 20km/h to 60 km/h in 10s. Its acceleration is​

Answer 1

Answer:

10/9m/sec^2

Explanation:

a= v2-v1/t

convert velocities into m/sec by multiplying v with 5/18

hope this answer helps you

Answer 2

Answer :-

Given :

• Initial speed = 20 km/h
• Final speed = 60 km/h
• Time taken = 10 s

To Find :

• Acceleration

Solution :-

Firstly, Converting the units -

• Initial speed = 20 km/hr = 20 × 5/18 = 5.55 m/s
• Final speed = 60 km/hr = 60 × 5/18 = 16.66 m/s

Substituting the value in formula :-

→ a = ( v - u ) / t

→ a = 16.66 - 5.55 / 10

→ a = 11.11 / 10

→ a = 1.1

Acceleration = 1 m/s²
