Answer:
12.5 km
Explanation:
Since 30.0 minutes is half of an hour and the average speed is 25.0 km/h we can multiply the time by the speed to find the distance travelled.
25.0km/h x 0.5 hours = 12.5 km
As an object falls toward earth, the potential energy of the object : Decreases
Here's the formula for the Potential energy :
E = Em + Ek + Eg
m = mass
= k kinetic
g = gravity
As the potential energy falls toward earth, the Eg became 0, which will decrease its amount
