Question

an object moves with a uniform speed of 10 metre per second for 5 seconds and then with a uniform speed of 5 metre per second for 10 seconds find the average speed​

Answer 1

Answer:

6.66m/s

Explanation:

1st case:-

10 m/s for 5 seconds

s = vt

= 10×5

= 50m

2nd case:-

5 m/s for 10 seconds

s = vt

= 5×10

= 50 m

Average velocity = total distance/total time

= 50+50/5+10

= 100/15

= 6.66 m/s
