The earth's radius is 6.37×10^6m; it rotates once every 24 hours. with the angular speed of 7.3 x 10^-5 what is the speed of a p
alexira [117]
The speed of the earth's surface located at 2/3 of the length of the arc between the pole which measure from the equator is 232.5 m/s.

Solution:
So the givens are, earth's radius = 6.37X10^6m, and the angular distance from the pole is 90 degrees. So 60 degrees is the 2/3.

r = 6.37x10^6 * cos(60) = 3.185x10^6m
since v = wr
v = 7.3x10^-5 * 3.185x10^6

v - 232.5 m/s

Explain Using the equation for translational kinetic energy, show why a car moving at 40 m/s has four times the translational ki
djverab [1.8K]

Answer:

Explanation:

Equation for translational kinetic energy = 1/2 m V² where m is mass and V is velocity .

In first case let mass of car be m

Translational kinetic energy = 1/2 m x 40² = 800 m .

In the second case ,

Translational kinetic energy = 1/2 m x 20² = 200 m

So , in former case kinetic energy of car is 4 times that of second case.

What is the difference between velocity and speed /vector and scalar? ​
stepladder [879]

Answer:

Speed only defines the magnitude of how fast an object is moving from one point to another. This is a scalar quantity (Only Value)

Velocity defines both how fast an object is moving and also in what direction the object is moving. This is a vector quantity (Value + Direction)
