Answer: -1.27 m/s^2
Explanation:
a = - V^2 / 2x
a = -(25^2) / 2 x (246) = 1.27 m/ s^2
Therefore the linear acceleration of the wheel is - 1.27 m/s^2
Answer:0.478 c
Explanation:
Given
mass of lighter Particle
mass of heavier Particle
speed of lighter particle
Let speed of heavier particle
and Momentum of the particle is given by





as momentum is conserved therefore 


Frequency is not a length of time. It's exactly the opposite.
Frequency tells you how often something happens. In fact,
the unit 'Hz' means 'per second'.
Frequency of 2 Hz means "It happens at 2 per second."
The time it takes for the thing to happen once is exactly the
'reciprocal' of the frequency ... ' 1 ' divided by the frequency.
If the frequency is 2 Hz, then the thing happens every 1/2 second.
If the frequency is 74 Hz, then it happens every 1/74 of a second.
If the frequency is 1 KiloHz, then it happens every 1/1000 second.
