<span>1.5 rev/s
Since angular momentum is conserved, the product of the moment of inertia and the rotational rate will remain a constant. So, assuming X as the desired rate of rotation we have:
X * 2.9 = 4.8 * 0.90
Now solve for X
X * 2.9 = 4.8 * 0.90
X * 2.9 = 4.32
X = 1.489655172
So when her arms and one leg go outward, her rotation slows to 1.489 rev/s. Rounding to 2 significant figures, gives 1.5 rev/s.</span>
Answer:
$900
Step-by-step explanation:
Use the formula for simple interest: i = p r t, where i is the interest earned, p is the principal amount, r is the interest rate as a decimal fraction, and t is the time in years.
Here, i = $27 = p(0.015)(2), or
$27 = 0.03p
Dividing both sides by 0.03, we get:
p = $27 / 0.03 = $900
The principal, in this situation, was $900.
