Levi and Clara are trying to move a very heavy box. Levi is pushing the box with a force of 30 N, and Clara is pulling the box w

ith a force of 50 N. The box exerts a frictional force of 65 N. Which best explains the forces? There is a net force of 15 N against them and they cannot move the box. There is a net force of 15 N allowing Levi and Clara to move the box. There is a net force of 65 N against them and they cannot move the box. There is a net force of 80 N allowing Levi and Clara to move the box.

A = force by which levi push the box = 30 N

B = force by which clara pulls the box = 50 N

f = frictional force acting on the box = 65 N

the pushing and pulling forces acts in same direction and the frictional force acts in opposite direction. hence the net force is given as

Net force = Sum of pushing and pulling force - frictional force

Net force = 30 + 50 - 65

Net force = 15 N


hence the correct choice is

There is a net force of 15 N allowing Levi and Clara to move the box.

What is the displacement of a NASCAR stock car after he completes the Indianapolis 500?
Mnenie [13.5K]

I'm such a devoted NASCAR fan that I don't even know if the starting line and finish line at Indy are the same line ... or maybe they're in different places, like the 100-meter sprint in track.

I have no idea, but I'm going to guess that the start and finish at Indy are the SAME line.  

If that's true, then the displacement of a car that runs the whole 500 miles is very close to <em>ZERO</em>.

Displacement is the distance and direction between the place where the object starts out and the place where it ends up.  The route it follows to get from the start to the finish is completely ignored, and doesn't matter.

(Do they the Indianapolis 500 in "stock" cars ? ?)

Neglect air resistance in this question. If you drop a ball from a height of 4.9 m, it will hit the ground 1s later. If you fire
olchik [2.2K]

Answer:

Explanation:

The time at which an object from from rest depends on air resistance, the height, gravity.

Since the question says we should neglect air resistance and both the ball and the bullet are from the same height they will get to the ground and the same time since they are both fired on earth which has the same gravity..

H=ut+1/2gt^2.

For an object dropping from a height the initial velocity is zero, therefore u=0m/s.

The formula becomes

t=√(2H/g)

So the time and object get to the ground depends on the height from the ground and gravity...

So since no air resistance they will get to the ground together.
