0.5mv^2
0.5 times 40 times 3^2
The kinetic energy is 180
Meiosis is the correct answer because of the fact all the other answers are no where near correct
this question is unclear. please specify.
Answer:
A protractor to measure the angle of the inclined plane with the horizontal
Explanation:
The student needs to lift the free end of the adjustable inclined plane until the object barely starts sliding, and measure the angle at which such happens. At that point, the force of friction equals the component of the weight in the direction of the incline. That is:
and
Then
and therefore, the coefficient of static friction is fully determined just by calculating the tangent of the angle that the incline forms with the horizontal.
Then the only extra instrument needed is a protractor to measure the angle.
Kinetic energy depends upon mass and velocity ! so the vehicle which has both the quality,has greatest KE !
