Question

starting from rest on a level road a girl can reach a speed of 5m/s in 10s on bicycle.find average speed during 10 sec and distance she traveled in 10sec

Answer 1

Answer:

average speed = 2.5 m/s

Distance traveled = 25 m

Explanation:

As average speed = total distance / total time taken

We have total time = 10 seconds

so we have to find total distance.

by using equation of motion v = u + at

we get value of acceleration = 0.5 m/s²

now by using equation of motion v² - u² = 2as

we get distance traveled = 25 m

now putting this value in average speed formula we get average speed = 2.5 m/s
