Answer:

Acceleration = change in velocity/change in time, a = (vf - vi)/t [Units: m/s/s or m/s2] .. Example: A car collides with an insect. If the car exerts a force of 10N on the insect what ... a level sidewalk at a constant speed of 1m/s if the frictional force is 400N? ... d) When the stick is hit slowly string 2 breaks because of the inertia of mass M.
