A cyclist can increase the speed of their bike in various ways such as, changing gears, positioning themselves properly, increase the pedalling rate
<h3>
Ways in which a cyclist can increase the speed of a bicycle</h3>
Bicycle riders could accelerate/ increase their speed in various ways
- By Changing the gears and by doing so increasing the speed
- By Positioning themselves in a streamlined manner, this is so that they become aerodynamic hence they cut across airflow.
- By increase the rate at which they are pedalling the bicycle.

<h2>Circular path i.e 1</h2>
Explanation:
If the driver steer into circular path , the acceleration of car will be
acceleration = velocity²/radius of circle
Because the velocity and radius of circle are both constant at all points . Thus the acceleration will also remain constant .
In case 3 and 4 , the radius of path changes . Because velocity is constant . Therefore the acceleration will not remain constant
Answer:
29.39 kg
Explanation:
From the question,
W = mg...................... Equation 1
Where W = weight of the cuboid box, m = mass of the cuboid box, g = acceleration due to gravity.
make m the subject of the equation
m = W/g.................. Equation 2
Given: W = 288 N
Constant: g = 9.8 m/s²
Substitute these values into equation 2
m = 288/9.8
m = 29.39 kg
