... A1500kg car moving at 15m/s collides with a utility pole and is brought to a rest in .3sec. Find the average force exerted on the car during the collision. F = (1500kg)(0m/s-15m/s)/.3sec = -75000N The negative sign means the force is in the opposite direction of the car’s velocity. Go over example 6 ...

Note that in the following three figures, which show
... We learned earlier that if an object is at rest, then the total of all the external forces acting on it must be zero. If we are also considering the possibility of rotational motion, we must add a second condition for a body at rest: The net torque of all the external forces acting on the body, wit ...
