Answer:
21.2m/s
Explanation
Given data
P=6.36 x 10⁴kg·m/s.
M=3000kg
From the momentum expression
P=mv
v=p/m
Substitute
v=63600/3000
v=21.2m/s
Hence the Velocity is 21.2m/s
Yes, you need to use the chain rule. Also you need to use the derivative of arcsin which is in tables.
Derivative of y = arcsin(x) = 1 / [√(1 - x^2)]
Chain rule: Derivative of archsin(cos(2x)) =
y' = 1 / [√(1 - (cos(2x))^2)] * derivative (cos(2x) =
y' = 1 / [√(1 - (cos(2x))^2)] * (- sin (2x)) * 2
y' = -2(sin(2x)) / [√( 1 - (cos(2x))^2]
Given what we know, as with all substances, the particles in the bowl of hot soup will slow down as they cool after being poured.
<h3>Why do particles slow when cooled?</h3>
- This has to do with energy.
- The soup particles are excited by heat energy.
- As the soup is poured, its heat energy radiates and it loses energy.
- Decreased energy causes the particles to slow down.
Therefore, the motion of the particles of the soup decrease or slows down as the soup cools due to the loss of energy they are experiencing. The soup radiates heat energy into the room or plate, causing the particles to lose energy and slow down.
