Good morning.
Lets make the movement function for the dog and cat.
The cat has a start position of1.5 m(the middle of the room), with an initial speed of 0 and acceleration of 0.85 m/s².
The dog has a start position of 0, an initial speed of 1.5 m/s and acceleration of -0.1 m/s².
<u>Cat:</u>
<u>Dog:</u>
Let's see if the dog reach the cat. Physically, it means
Now we solve for <em>t</em>:
We have a negative Delta. Therefore, there is no instant t when the dog reaches the cat.

Answer:
(a) k =
(b) τ = ∝
Explanation:
The moment of parallel pipe rotating about it's axis is given by the formula;
I = ---------------------------------1
(a) The kinetic energy of a parallel pipe is also given as;
k = --------------------------------2
Putting equation 1 into equation 2, we have;
k =
k =
(b) The angular momentum is given by the formula;
τ = Iw -----------------------3
Putting equation 1 into equation 3, we have
τ =
But
τ = dτ/dt = ------------------4
where
dw/dt = angular acceleration =∝
Equation 4 becomes;
τ = ∝
