Answer:
The magnitude of the rate of change of the child's momentum is 794.11 N.
Explanation:
Given that,
Mass of child = 27 kg
Speed of child in horizontal = 10 m/s
Length = 3.40 m
There is a rate of change of the perpendicular component of momentum.
Centripetal force acts always towards the center.
We need to calculate the magnitude of the rate of change of the child's momentum
Using formula of momentum
Put the value into the formula
Hence, The magnitude of the rate of change of the child's momentum is 794.11 N.
Answer:
a)
b)Does not affect the long term.
Explanation:
Given that
A = A0 cos(ωt)
This is linear equation so integration factor ,I
Now by using linear equation property
b)
at t= 0
So the initial condition does not affect the long term.
