Answer:
The acceleration of the biker is 2.67m/s² while that of the car is 3.75m/s². So, the acceleration of the biker is NOT HIGHER than that of the car.
Step-by-step explanation:
Given that,
acceleration of biker A= ?
Initial velocity of biker Vi = Om/s
Final velocity of biker Vf = 8m/s
Time taken (t) = 3 seconds
Since acceleration is the rate of change of velocity per unit time
i.e Acceleration = (Vf - Vi) / t
A = (8m/s - 0m/s) / 3s
A = 2.67 m/s²
To know which is higher, calculate the acceleration of the car
acceleration of car A= ?
Initial velocity of car Vi = Om/s
Final velocity of car Vf = 30m/s
Time taken (t) = 8 seconds
Acceleration = (30m/s - 0m/s) / 8s
A = 30m/s / 8s
A = 3.75 m/s²
Since, the acceleration of the biker is 2.67m/s² while that of the car is 3.75m/s², the acceleration of the biker is NOT HIGHER than that of the car.
