Answer:
Friction
Explanation: is the force that opposes motion between any surfaces that are in contact. There are four types of friction: static, sliding, rolling, and fluid friction. Static friction acts on objects when they are resting on a surface.Nov 3, 2021
Answer:
P=627.47W
Explanation:
To solve this problem we have to take into account, that the work done by the winch is
the force, at least must equal the gravitational force
with force the tension in the cable makes the winch go up.
The work done is
To calculate the power we need to know what is the time t. But first we have to compute the acceleration
The acceleration will be
and the time t
The power will be
HOPE THIS HELPS!!
The force that will make this into
equilibrium would be equal to the force of equal amount yet applied on the
opposite direction.
<span>So we are given that a force of 55 N due west
was applied, so the equilibrium force would be 55 N due east.</span>
