Answer:
Hooke's law states that the applied force F equals a constant k times the displacement or change in length x, or F = kx. ... Hooke's law describes the elastic properties of materials only in the range in which the force and displacement are proportional.
Explanation:
Velocity_slowing down_284cm per sec sw
Answer:
if the weight of the object is equal to the force applied, there will be no change
if the force applied is less than the weight of the object, there won't be any change
if the force application ed is greater than the weight of the object, than the object will move.
Explanation:
here the weight referred to the force of the object.
Answer:
the safe's coefficient of kinetic friction on the bank floor is
Explanation:
GIven that:
Bonnie and Clyde are sliding a 325 kg bank safe across the floor to their getaway car.
So ,let assume they are sliding the bank safe on an horizontal direction
Clyde → Δ(bank safe) → Bonnie
Also; from the above representation; let not forget that the friction force is acting in the opposite direction ←
where;
=
The safe slides with a constant speed
If Clyde pushes from behind with 377 N of force while Bonnie pulls forward on a rope with 353 N of force.
Thus; since the safe slides with a constant speed if the two conditions are met; then the net force acting on the slide will be equal to zero.
SO;
Since the net force acting on the slide will be equal to zero.
Then;
Also; let and
Then;
where;
Then;
Thus; the safe's coefficient of kinetic friction on the bank floor is
