Answer:
Explanation:One method of calculating average speed is to divide the total distance by the total time spent
d1=d2= 12 miles
d1=d2= 19312.1 m
There is slight difference between the average speeds due to the reason that average speed is not just the midpoint of the speed but is the total distance traveled by total time.
Potencial Energy=hma
Where
Potencial Energy =E= 54.9J
h=?
m=8kg
a=9.8m/s^2
You need to know that 1 J=1(kgm^2)/s^2
Isolate h=E/(ma)
h=(54.9)/(8*9.8)
The answer is A,B,C that apply. I believe this is the answer i hope this helps have a good day.
I had this question before I think was it A or B.
Answer:
They will both bounce back at the same speed they had before the collision
Explanation:
Assuming an elastic collision, kinetic energy will be conserved. Therefore, the billiard balls will have the same speed after the collision as before the collision.
