You pushes a 25kg box with 40 N of force, but the friction on the crate is 15 N. What is the net
force?
Answer:
25 N in the direction of your push
Explanation:
The friction force acts against your pushing force....it reduces the net amount of force you are exerting
Net force = 40 - 15 = 25 N

does anyone know this whole distance and displacement concept it makes zero sense
Answer:
Distance is the total length travelled, or in other words, it is a measure of how far apart two objects are.
Displacement, on the other hand, the difference between the starting and and ending positions of an object.
For example, if a person walks 10m forwards, then 7m backwards, thereby ending up where he started, he will have travelled a distance of
10 + 7 = 17m .
But the difference between his starting and finishing positions is
10 - 7 = 3m.
If, however, the man walked 10m forwards and then 10m backwards, the distance he covered would be 10 + 10 = 20m, but the displacement would've been 0 as there would be no difference between his starting and ending positions.
Let me know if you still don't understand.
Which equation can be used to calculate the normal force on an object if you know the speed of the object, the coefficient of kinetic friction, and the force of kinetic friction on the object?
Answer:
D
Explanation:
The friction force is the weight force times the coefficient of friction. So diving by the coefficient gives you the weight force which is equivalent to the normal force.
The equation that we can used to determine the frictional force using the coefficient of kinetic friction and the normal force is given by the expression : F = u N.
Where N is the normal force by the weight of the body.
What is frictional force?Frictional force is a type of force acting on a body to prevents its motion. Hence, the frictional force is always negative. Frictional force acting on an object is making a resistance to the motion of the object.
There are both kinetic frictional force and static frictional force. The coefficient of frictional force is the ratio of the frictional force to the normal force on the object. The normal force on the object is equal to m g that is the force by its own weight.
If u is the coefficient of kinetic friction and N be the normal force acting on the object, then the force of kinetic frictional force F is given by,
F = u N.
Where N = mg.

a) Describe the energy change of the ball from the point of release to the top of the rebound
b) What can you say about the energy of the ball at the point of release compared with at the top of the rebound?
a)The ball's potential energy changes as it moves from the release point to the top of the rebound.
b)The ball's potential energy is at its highest and rests when it is in the top position.
What is potential energy?The potential energy is due to the virtue of the position and the height. The unit for the potential energy is the joule.
The potential energy is mainly dependent upon the height of the object.
Potential energy = mgh
The kinetic energy of the body is due to the virtue of motion.
According to the Law of Conservation of Energy, energy can neither be created nor destroyed but can be transferred from one form to another.
The total energy is the sum of all the energies present in the system. The potential energy in a system is due to its position in the system.
A ball dropped onto a trampoline returns to the same height after the rebound.

What is the total work done on the object? 1)10 J 2) 14 J 3) 28 J 4) 56 J I found the resultant of the two distances, which is 5 m, I used 5 m * 2 N=10 J, but it’s not the answer. 2. A 20-newton block is at rest at the bottom of a frictionless incline, since I can’t show you the diagram, I will describe it. Supposed a right triangle, the vertical height is 3 m, and the base is 4.0 m. Then the hypotenuse is the incline and the block is at the bottom. The question is: How much work must be done against gravity to move the block to the top of the incline? I know that conservative forces are forces for which the work done does not depend on the path taken but only on the initial and final positions. But here I Know I should use 3 m * 20N=60 J. but the thing is it starts from the bottom which is the bottom of the incline, and ends at the top, then it should be the length of the hypotenuse? But if it’s 3 m, then it should have started from left end of the base, not the right end of the base which is the bottom of the incline.
