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 ? ?)
F = force applied to lift the box = weight of the box = 88 N
P = power produced while lifting the box upward = 72 Watt
v = speed of the box = ?
Speed of the box is given as
v =
inserting the values
v =
v = 0.82 ms⁻¹
Answer:
all of the particles are at rest (v = 0)
Explanation:
Therefore, since nothing is moving, the total momentum of the system must also be zero.
Answer:
The pressure is .
Explanation:
Calculate the area of the rectangular container.
A=LB
Here, L is the length and B is the breadth.
Put L=0.125 m and B= 0.209 m.
A=(0.125)(0.209)
The expression for the pressure in terms of area and force is as follows;
Here, P is the pressure and F is the force.
Put and F= 4.47 N.
Therefore, the pressure of the given sample is .
Nearly all light that strikes a transparent object will be absorbed by the object.
