A 20-pound object is dropped from a 50-foot bridge onto the ground below it. A 50-pound object is dropped from a 100-foot cliff

ira [324]

The 50 pound object will reach the ground first.

Explanation:

Using the second equation of motion, we can derive the time taken for each of the object to reach the ground. As the object is thrown from the top of the bridge or cliff, acceleration due to gravity will be acting on them.

So, $s = ut+\frac{1}{2} at^{2}$

The value of s for the object thrown from 50 foot bridge is given as 50 ft. The initial velocity of the object will be zero. The acceleration can be written as the ratio of mass to gravitational force.

Then, $s = (0) t +\frac{1}{2}*\frac{m}{F}*t^{2}$

$50 = \frac{20}{2F} t^{2} \\\\t^{2} = \frac{100F}{20}$

$t = \sqrt{5F}$

Then, consider the time taken for the 50 pound object to reach the bottom of 100 ft cliff as t₁ and the displacement in this case is 100 ft.

Then, $100 = (0)t +\frac{1}{2}*\frac{50}{F}*t_{1}^{2} \\\\t_{1}^{2} =\frac{200F}{50}$

$t_{1} = 2 \sqrt{F}$

Since, the gravitational force acting on both the objects will be same, the ratio of time taken is

$\frac{t }{t_{1} }=\frac{\sqrt{5F} }{2\sqrt{F}} = \frac{\sqrt{5} }{2}$

So, the time taken for the 20 pound object to reach the ground of 50 ft bridge is √5 s =2.236 s and the time taken for the 50 pound object to reach the ground of 100 ft cliff is 2 s.

Thus, the 50 pound object will reach the ground first.

The specifications for a product you are developing require that the cross-section area cannot be greater than 12 in2. You have

Temka [501]

Answer:

=IF(B3*C3<=12, "Yes", "No")

Explanation:

Image for the question is attached here

Complete question

The specifications for a product you are developing require that the cross-section area cannot be greater than 12 in2. You have summarized the dimensions of 5 prototypes you have made. Column D has an equation to determine if your product meets specifications. It indicates that only specimen #5 meets the specifications.

What is the equation in cell D3?

Solution

As we can see in the table,

For all those tests in which the product of corresponding cell values in column B and C under the heads vertical and horizontal dimension respectively is less than $12$ square inch the column D values is "No". That is it does not meet the specification. Here specification is "cross-section area cannot be greater than 12 in2"

Here IF function is used for conditional formatting.

Thus, the formula in the cell must be

=IF(B3*C3<=12, "Yes", "No")
