The function s(t) represents the position of an object at time t moving along a line. suppose s( 1 )=123 and s( 3 )=173. find the average velocity of the object over the interval of time [1,3]?

The average velocity is .

Explanation:

The average velocity is calculated in the following way:

If represents the position of an object at time ,

and ; , the average velocity is defined in that interval as:

Taking the data from the question:

.

mass and volume are the answers you are looking for

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
