First I’ll show you this standard derivation using conservation of energy:
Pi=Kf,
mgh = 1/2 m v^2,
V = sqrt(2gh)
P is initial potential energy, K is final kinetic, m is mass of object, h is height from stopping point, v is final velocity.
In this case the height difference for the hill is 2-0.5=1.5 m. Thus the ball is moving at sqrt(2(10)(1.5))=
5.477 m/s.
Answer:
the answer is A & C & E just did the lab
Explanation:
Answer:Sales tax, value-added tax, excise tax, and customs duties are examples of indirect taxes.
Explanation:
x(2) = 30(2) = 60 m
y(2) = ½(-9.8)2² = -19.6 m
x(4) = 30(4) = 120 m
y(4) = ½(-9.8)4² = -78.4 m
x(6) = 30(6) = 180 m
y(6) = ½(-9.8)6² = -176.4 m
x(8) = 30(8) = 240 m
y(8) = ½(-9.8)8² = -313.6 m
x(10) = 30(10) = 300 m
y(10) = ½(-9.8)10² = -490 m
Carbon dioxide is the most abundant greenhouse gas in the atmosphere.
