A machinist turns the power on to a grinding wheel, at rest, at time t = 0 s. The wheel accelerates uniformly for 10 s and reaches the operating angular velocity of 58 rad/s. The wheel is run at that angular velocity for 30 s and then power is shut off. The wheel slows down uniformly at 1.4 rad/s2 until the wheel stops. In this situation, the total number of revolutions made by the wheel is closest to:

Answers

Answer 1
Answer: The wheel accelerates uniformly for 10s and reaches the operating angular velocity of 58 rad/s. The wheel is run at that angular velocity for 21s and then power is shut off. The wheel slows down at 2.4rad/s^2 until it stops.

I got a special question for you 2y * 3y + 4y

Answers

Answer:

6y^2 + 4y.

Explanation:

To simplify the expression 2y * 3y + 4y, we follow the order of operations, which is often remembered as PEMDAS (Parentheses, Exponents, Multiplication and Division from left to right, Addition and Subtraction from left to right).

1. Multiplication:

First, we simplify the multiplication within the expression.

2y * 3y = 6y^2

2. Addition:

Next, we add the remaining term, which is 4y.

6y^2 + 4y

So, the simplified expression is 6y^2 + 4y.

Please note that there are no like terms (terms with the same variable and exponent) within this expression, so we cannot further combine or simplify the terms.
6y^2 + 4y

First multiply the coefficients, which 2*3 is 6. Y time y is y^2. Keep the 4y, which brings your answer to 6y^2 + 4y.

A piece of equipment costs $30,000, and is expected to generate $8,500 of annual cash revenues and $1,500 of annual cash expenses. The disposal value at the end of the estimated 10-year life is $3,000. Ignoring income taxes, the payback period is:.

Answers

Answer:

C. 4.29 years

Explanation:

The computation of the payback period is shown below:

Payback period = Initial investment of the equipment ÷ Cash flows

where,

Initial investment = $30,000

And, the cash flows is

= $8,500 - $1,500

= $7,000

So the payback period is

= $30,000 ÷ $7,000

= 4.29 years

By dividing the initial investment by the cash flows we can get the payback period and the same is applied above.
