The free fall acceleration of an object under the influence of earths gravity 9.81. What is it’s value in I’m/min^2

1 answer:

4 0

Answer:It means that the speed of a free falling object (an object only under the influence of gravitational force) increase at the rate of 9.8m/sec per second.

So the object will be traveling at 9.8m/sec just after 1st second is passed.

It would be traveling at 9.8m/s +9.8m/s =19.6m/s just after 2nd second.

It would be traveling at 19.6m/s + 9.8/s=29.4 m/s just after 3rd second,and so on .

Answer:

840 cubic inches

Step-by-step explanation:

Given:

The wooden steps have two parts.

Both of which are rectangular prisms.

The top part is 6 inches tall, 5 inches wide and 10 inches long.

The bottom part is 6 inches tall, 9 inches wide and 10 inches long.

Question asked:

What is the volume of the steps?

Solution:

For top part

Length = 10 inches

Width = 5 inches

Height = 6 inches

As we know:

$Volume\ of\ rectangular\ prism =length\times width\times height$

$=10\times5\times6=300\ cubic\ inches$

For bottom part

Length = 10 inches

Width = 9 inches

Height = 6 inches

Similarly

$Volume\ of\ rectangular\ prism =length\times width\times height$

$=10\times9\times6=540\ cubic\ inches$

Volume of two steps = 300 + 540 = 840 cubic inches

Therefore, the volume of the steps are 840 cubic inches.
