Question

11. A cyclist accelerates from 0 m/s to 10 m/s in 3 seconds. What is his acceleration ? Is this acceleration higher than that of a car which accelerates from 0 to 40 m/s in 8 seconds?​

Answer 1

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

v = final velocity

u = initial velocity

t = time taken

the acceleration of the cyclist is

`(10 - 0)/(3) = 3.333333....`

approximately 3.33 m/s^2

the acceleration of the car is

`(40 - 0 )/(8) = 5.0`

5.0 m/s^2

`5.0 > 3.33 \\ so \: the \: answer \: is \: no`
