Aperson drives 4 miles to the mall. if the speed limit is 45 miles/hr and the person
makes the trip in .03 hours. is the person breaking the speed limit?
yes, the person is going 150 miles/hr.
o no, the person is going 1 mile/hr.
yes, the person is going 133 miles/hr.
o no, the person is going 40 miles/hr.

Third Option

Yes, the person is going 133 miles/hr.

Explanation:

Remember that the average speed can be calculated as

Where s is the speed

d is the distance traveled

t is the time

In this case

Therefore

Remember that the speed limit is 45 miles/hr

So the answer is the third option "Yes, the person is going 133 miles/hr".

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.
