With an average acceleration of -0.50m/s^2, how long will it take a cyclist to bring a bicycle with an initial speed of 13.5m/s to a complete stop?

given that

acceleration = - 0.50 m/s^2

v = 13.5 m/s

so final speed will become zero after it completely stop

so here we can use kinematics

so cycle will completely stop after t = 27 s

probably not the "magnets"in the magnet, so to speak, are thought to be electrons orbiting in shells. vurrent loops two sides to the loop
