Question

Q2 ) Starting from rest on a level road a girl can reach a speed of 5m/s in 10 s on her bicycle, find

A) the acceleration​

Answer 1

0.5m/s²

Step-by-step explanation:

Given parameters:

Initial velocity = 0m/s

Final velocity = 5m/s

Time taken = 10s

Unknown:

Acceleration of the bicycle = ?

Solution:

Acceleration is the rate of change of velocity with time.

Acceleration =
`(v - u)/(t)`

v is the final velocity

u is the initial velocity

t is the time taken

Insert the parameters and solve;

Acceleration =
`(5-0)/(10)` = 0.5m/s²
