The heaviest planet in the world is Jupiter!
Working displayed in the picture below, the answer is -11 m s^-2
Answer:
There is much more friction on the rough surface than there is on the smooth surface.
Explanation:
Given :
Initial speed , u = 0 m/s .
Final speed , v = 91 km/h = 25.28 m/s .
To Find :
a) Average acceleration .
b ) Assuming the motorcycle maintained a constant acceleration, how far is it from the traffic light after 3.3 s .
Solution :
a )
We know ,by equation of motion :

b)
Also , by equation of motion :

Hence , this is the required solution .
