1. If the two wagons have the same kinetic energy, then:
KE(blue)=KE(red)
1
1
ππ π£π 2 = ππ π£π 2
2
2
Solve for the velocity of b:
ππ π£π 2 = ππ π£π 2
π£π = β

ππ π£π 2
ππ

ππ
π£π = π£π β
ππ
Since the coefficient of the velocity of red is greater than zero, the velocity of blue is
greater.
2. Use this equation, plugging in the respective variables:
πΎπΈ =

ππ£ 2

(500ππ)
πΎπΈ =

KE=1954966.225 J
3.
Write down the givens:
M=3.67kg
H=4.98m
The equation we need is:
1
πΎπΈ = ππ£ 2

πΎπΈ = (3.67ππ)(? )2

We donβt know the velocity when it str...
