Question

a bus is moving with a speed of 25 km per hour if its speed becomes 40 kilometre per hour in 6 second at acceleration of bus​

Answer 1

Answer:

0.694 m/s²

Explanation:

a= v-u/t

• First, we will change the unit hour into seconds. So, 1 hour= 3600 seconds = 6*3600 = 21600
• Now, we will convert km into m. 1 km= 1000 m. So, 25 km= 25000 m and 40 km= 40000 m
• Now let's use the formula a=v-u/t

u= 25000 m/s

v= 40000 m/s

t= 21600 second

a= 40000- 25000/21600 m/s²

= 15000/21600 m/s²

= 0.694 m/s²
