You are riding a bicycle. you apply a forward force of 150 n, and you and the bicycle have a combined mass of 90 kg. what is the acceleration of the bicycle?

Answer

1.667 m/s²

Using the Newton's second law of motion;

force is directly proportional to the rate of change of momentum and it takes place in the direction of force.

i.e F = change in momentum

F = (mv - mu)/t

   =m(v-u)/t

   = ma

∴ F =ma

  a = F/m

      = 150/90

      = 1.667 m/s²

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
