While decorating her apartment, Becca pushes her 95 kg cabinet across the floor at a constant speed. The coefficient of friction between wood on wood is 0.75. what force must she exert to overcome friction?
698.25 N
584.67 N
1000 N
255.98
In problem # 3, why would it have been harder just to get the cabinet to move from a standstill?
because the static coefficient of friction is greater than the sliding coefficient of friction.
because the sliding coefficient of friction is greater than the static coefficient of friction.
because Becca is stringer when she is standing still.
because it is easier to push things across wood than it is to push things across carpet.

1500 kg
900 kg
425 kg
I thought that the acceleration of gravity was 9.8 m/s/s. Why does an object dropped from something high up, like from a plane, will reach a point where it won't accelerate anymore (terminal velocity)?
because objects slow down as they fall.
because the weight force is greater than the drag force.
because the drag forces are more than the weight force.
because the drag forces will balance out the weight.
