What is the acceleration of the motorcycle in section CD?


What Is The Acceleration Of The Motorcycle In Section CD class=

Sagot :

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
