Answer:
Part a)
acceleration = -0.042 m/s/s
Part b)
initial speed = 14.17 m/s
final speed = 5.77 m/s
Explanation:
Part a)
Let the initial velocity of the motorcycle is
now at the end of 80 s let the speed is
after another 120 s let the speed will be
now we know that
also we know that
also we have
now we can say
also we know
Part b)
now we have
so the starting velocity of the trip is
now speed after t = 200 s is given as
