2. Acyclist accelerates from 0m/s to 8m/s In 3 seconds. What is his acceleration? Is this acceleration higher than that of a car which accelerates from o to 27m/s in 8 seconds?

Question

Answer 1

### The cyclist's acceleration is

and the car's acceleration is

. The car's acceleration is higher.

Answer 2

## Step 1: Calculate the acceleration of the cyclist### Use the formula for acceleration:

, where

is the change in velocity and

is the change in time. For the cyclist,

and

. Thus,

.## Step 2: Calculate the acceleration of the car### Similarly, for the car,

and

. Thus,

.## Step 3: Compare the accelerations### Compare the two accelerations:

and

. Simplify the fractions to compare:

and

. The car's acceleration is higher.
