Hi there!
a)
We can find the angular velocity at t = 2.0 s by plugging in this value into the equation.

b)
The angular acceleration is the derivative of the angular velocity, so:

Thus, the angular acceleration is a <u>constant 25 rad/s².</u>
Answer:
scientists will use absolute dating to find how old a fossil exactly is.
Answer:
(a) v = 15m/a
(b) No they won't feast because the rock can only rise to a height of 11.5m which is less than 15m.
