Assume that energy losses (due to aerodynamic resistance or bearing friction are negligible).
At the highest point, the pendulum has its maximum potential energy (PE) and zero kinetic energy (KE). The total energy is equal to the PE = 141 J.
At the lowest point, the pendulum has its maximum KE, and zero PE. The total energy is equal to the KE.
Because energy is preserved, therefore
KE at the lowest point = PE at the highest point = 141 J.
Answer: 141 J
Mike was running at a higher speed than Mitchell
I guess since I couldn't see red, I might see the red stripes as white or maybe not even see them at all.
F = M A
Force = (mass) x (acceleration)
= (1,650 kg) (4 m/s²) = 6,600 kg-m/s² = 6,600 Newtons
Answer:
False
Explanation:
While most foods can be classified as "good" or "bad" for our bodies, some foods are more complicated. Some healthy foods could be bad for you if you're allergic to them, and other foods could have both positive and negative effects on your body.
