Answer:
, 
(before collision), 
(after collision).
Explanation:
The total momentum is obtained using the Principle of Momentum Conservation:
It is trivial to find that final speed and total momentum of the system are zero:
The total kinetic energy of the system becomes zero due to the inellastic collision and the same masses and speeds. Total kinetic energies before and after collision are, respectively:
Answer:
1 N
Explanation:
1) You'll just have to sum the force vectors, and since they are opposite, you'll calculate the difference of their magnitudes, in absolute value.
Ftot = |F1 - F2| = 6N - 5N = 1N
2)The direction will be the same as the greater force's direction.
The correct answer is Reagan is right because sound waves are compressional waves.
Reason is because Sound is transmitted through gases, plasma, and liquids as longitudinal waves, also called compression waves. It requires a medium to propagate. Through solids, however, it can be transmitted as both longitudinal waves and transverse waves.
Answer:
<em>199,430Joules</em>
Explanation:
Gravitational potential energy is the energy possessed by a falling object due to virtue of its position.
gravitational potential energy = mass * acceleration due to gravity * height
gravitational potential energy = 55 * 9.8 * 370
gravitational potential energy = 539 * 370
gravitational potential energy = 199,430
<em>Hence the total change in the skier's gravitational potential energy is 199,430Joules</em>
