Tyler slides across his kitchen floor. the coefficient of kinetic friction between his socks and the tile is 0.3. if his mass is 67 kg, what is the force of friction acting on him?

The force of friction acting on Tyler is given by:
(1)
where  is the coefficient of friction, and N is the normal force exerted by the floor on Tyler. However, the normal force is equal to Tyler's weight:

where m is Tyler's mass and g is the gravitational acceleration. Therefore, the frictional force (1) becomes

The objects do not reach terminal velocity         there is not enough time from the time the object falls from when it hits the ground to achieve terminal velocity. an object must be placed higher to achieve terminal velocity in order to be in free fall.
