Answer:
30m/s²
Explanation:
The acceleration of the motorcycle in section CD is the slope of the velocity - time graph.
Given that;
Initial velocity = 20m/s Time = 6s
Final velocity = 50m/s Time = 7s
The time interval = 7s - 6s = 1s
So;
Acceleration = [tex]\frac{Change in velocity }{time}[/tex] = [tex]\frac{50 - 20}{1}[/tex] = 30m/s²
