Question

A cyclist accelerates from 0 m/s to 8 m/s in 3 seconds. What is his acceleration ? Is this
acceleration higher than that of a car which accelerates from 0 to 30 m/s in 8 seconds?

Answer 1

cyclist. (8-0)/3 == 8/3 = 2.667

car (30-0)/8== 30/8 ) =3.75

no , acceleration of car is higher .

Answer 2

Answer:

Explanation:

acceleration formula = $\frac{final speed - initial speed}{time taken}$

according to the formula,

8-0/3 = 8/3 $\frac{m}{s^{2} }$ => is the acceleration of the cyclist,

30-0/8 = 30/8 $\frac{m}{s^{2} }$ => is the acceleration of the car.

let's compare them by first making the denominator common,

$\frac{90}{24} > \frac{64}{24}$

Hence, the acceleration of cyclist is not higher than that of the car.
