1. If the two wagons have the same kinetic energy, then:

KE(blue)=KE(red)

1

1

ππ π£π 2 = ππ π£π 2

2

2

Solve for the velocity of b:

ππ π£π 2 = ππ π£π 2

π£π = β

ππ π£π 2

ππ

ππ

π£π = π£π β

ππ

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:

πΎπΈ =

1

ππ£ 2

2

1

π 2

(500ππ)

πΎπΈ =

(88.43 )

2

π

KE=1954966.225 J

3.

Write down the givens:

M=3.67kg

H=4.98m

The equation we need is:

1

πΎπΈ = ππ£ 2

2

1

πΎπΈ = (3.67ππ)(? )2

2

We donβt know the velocity when it str...
