Answer:
C. 8.01 m/s²
Explanation:
vf²= vi² + 2 • a • d
2ad = vf² - vi²
a = (vf²- vi²)/2d
d=25.00 -5.00=20.00 m
vi =0
vf=17.90 m/s
a =(17.90² -0²)/(2*20) = 8.01 m/s²

Answer:
I think the answer is "A roller coaster going up a hill"
Explanation:
Because the roller coaster is losing kinetic and losing potential enregy.
Answer:
9.81N
Explanation:
the force of attraction is given by
F=<u>GmM</u><u>/</u><u>R²</u><u> </u>
where m is mass of the body
M is mass of the earth
R is radius of the earth
G is the universal gravitational constant(6.67x10-¹¹)
hence we substitute the values in the formula.

Answer:
0.5 meters
Explanation:
W=Fd, where W is work, F is force, and d is distance.
5J=10N * x
x= 5J/10N=0.5m
Hope this helps!
