WebThis formula is interesting since if you divide both sides by t t, you get \dfrac {\Delta x} {t}= (\dfrac {v+v_0} {2}) tΔx = ( 2v +v0). This shows that the average velocity \dfrac {\Delta x} {t} tΔx equals the average of the final … WebA box slides down a plank of length d that makes an angle of θ with the horizontal as shown. μ k is the kinetic coefficient of friction and μ s is the static coefficient of friction.

An object shot straight up (stays in the air a long time) will actually have a final speed slower than the initial speed. The lower the angle the less flight times, so the final speed will be closer to the initial speed.
