Which of the following is not a an example of dissipated energy?
b. kinetic

b. all of the energy can be accounted for
Answer:
67.6 m
Explanation:
For this problem, we just need to analyze the motion of the two planes after the collision.
The two planes stick together and move with a velocity of
u = 19.3 m/s
The problem tells us that they skid until they stop: so, their final velocity is
v = 0
Since the velocity is not constant, this means that they are accelerating.
We also know that they skid for a time of
t = 7 s
Therefore, we can find their stopping distance using the following suvat equation
And substituting, we find
Newton's Third Law- For every action there is an equal and opposite reaction... Does this answer your question? If not, I can explain further...
Answer:
kinetic energy (K.E) = 5.28 ×10⁻¹⁷
Explanation:
Given:
Mass of α particle (m) = 6.50 × 10⁻²⁷ kg
Charge of α particle (q) = 3.20 × 10⁻¹⁹ C
Potential difference ΔV = 165 V
Find:
kinetic energy (K.E)
Computation:
kinetic energy (K.E) = (ΔV)(q)
kinetic energy (K.E) = (165)(3.20×10⁻¹⁹)
kinetic energy (K.E) = 528 (10⁻¹⁹)
kinetic energy (K.E) = 5.28 ×10⁻¹⁷
