If the speed is constant, then the forces on the crate are balanced, i.e. they add up to zero.
Since the kinetic friction force is 10N, then the puller must be pulling the crate with an equal force of 10N.
If he continues pulling with the force of 10N through a distance of 10 m, then the work he does is
(10 x 10) = 100 newton-meters or 100 joules.
The mass of the crate is utterly irrelevant to the discussion.
Kinetic friction.
2.5 m/s/s.
If there is no friction or anything that can impede the movement off the object, then the force is zero. If there is friction, then the force is equal to that of the friction.
false. Kinetic friction is the friction acting upon a moving object. It would be the frictional force against you if you pulled a box across a table. Static friction is the frictional force needed to overcome to get an object at rest into motion.
Ignore the kinetic friction coefficient, that is only in the problem to trick you. If the force pulling the sled is parallel to the ground, then the problem should be pretty easy. Acceleration due to gravity = 9.8 m/s^2
It could have kinetic energy when the strings are being pulled and it is in operation

Potential.
Trick question; the earth is round and doesn't have any edges.
