Suppose you take a trip that covers 180 km and takes 3 hours to make. Your average speed is
8. 33 m/s
b. 16.66 m/s
c. 27.78 m/s
d. 41.67 m/s

v = 16,66 m/s

Explanation:

To obtain the velocity of the train we must use the velocity formula for a uniform line movement:

v = x/t

Where x is the space and t is time.

replacing given values:

v = 180 km / 3 h

v = 60 km/h

to pass this value to international units:

v = 60 / 3,6 m/s

v = 16,66 m/s

i think the answer is a, hope this is right, that would be my best guess.

f is prop to m1xm2 double m1 double force
