force = mass x acceleration mass = force / acceleration acceleration = force / mass A 20 kg bike is moving at of 11 m/s². What force does it have? mass = 20 kg acceleration = 11 m/s2 force = ?

220 N is the force

Explanation:

F=m x a

wvbbvvv

acceleration = (change in speed) / (time for the change)

change in speed = (20-120)= -100 m/s.

1.5 min = 90 sec

acceleration = -100/90 = -1.11 m/s^2.

we don't care about the 150kg or the 2,500 meters. they don't make any difference.
