Answer:
Acceleration of the cyclist: 2.67 m/s²
The acceleration of the cyclist is lower than that of the car.
Step-by-step explanation:
- Acceleration refers to the rate of change in velocity of a body in motion.
- It is calculated by; dividing the change in velocity by time.
- Acceleration = (Final velocity - Initial velocity) ÷ time
In this case;
For the cyclist;
Initial velocity = 0 m/s
Final velocity = 8 m/s
time = 3 seconds
Therefore;
Acceleration = (8 m/s - 0 m/s) ÷ 3 seconds
= 2.67 m/s²
For the car;
- Initial velocity = 0 m/s
- Final velocity = 30 m/s
- Time = 8 seconds
Therefore;
Acceleration = ( 30 m/s - 0 m/s) ÷ 8 seconds
= 3.75 m/s²
The acceleration of the cyclist is lower than that of the car.
