How much work is done lifting a 100 Newton book onto a shelf that is 2 meters high on Earth?

Mathematics

4 0

We want to find the work done by lifting a book a given distance.

The answer is 200 N*m

We know that the book weighs 100 Newtons and that we lift it a distance of 2 meters.

Remember that the work needed to lift an object of mass M to a height H is:

W = M*g*H

where g is the gravitational acceleration.

Knowing that:

weight = M*g

We can replace the things we know to get the work:

W = 100N*2m = 200 N*m

How much more would $8,000 earn in four years compounded daily at 5% than compounded annually at 5%?
QveST [7]

Answer:

Given the statement:

8,000 earn in four years compounded daily at 5%

To find the amount we use formula:

A = P(1+\frac{r}{n})^{nt}

where P is the principal , A is the amount , n is number of times compounded per year and t is the time in year.

Here, Principal(P) = $8000, r = 5% and n = 365

Substitute these given values we get;

A_1= 8000(1+\frac{5}{365})^{365 \cdot 4}

A_1= 8000 \cdot 1.000137^{1460}

A_1= 8000 \cdot 1.22141

Simplify:

A_1= \$9771.28

To find the Interest we use formula:

I_1= A_1-P

I_1= 9771.28 -8000 = \$1771.28

It is also given that:

8,000 earn in four years compounded annually at 5%.

Here, P = $8000, r = 5% , t =4 year and n = 1

Using the same formula to calculate the amount:

A_2 = 8000(1+\frac{5}{1})^{1 \cdot 4}

A_2= 8000(1.05)^4

Simplify:

A_2= \$9724.05

To find the Interest :

I_2= A_2 - P

I_2= 9724.05 - 8000= \$1724.05

Then;

I_1-I_2 = 1771.28-1724.05 = \$47.23

Therefore, $47.23 more would  $8,000 earn in four years compounded daily at 5% than compounded annually at 5%
