Wile E Coyote (below) has a mass of 12.5 kg and is on a hill with a height of 55 m above a valley. He wants to reach Road Runner, who is on a hill with a height of 100 m on the other side of the valley, by using an ACME rocket attached to some wheels. Assume that friction is negligible. a) What is the potential energy of Wile E Coyote when he is on the 55-m ill and what would be his potential energy if he reaches the 100-m hill? b) What is the minimum initial speed (provided by the rocket) that would allow Wile E Coyote to reach the other side? c) If the initial speed of Wile E Coyote is 25 m/s, what is his speed at the bottom of the valley? 100m 55m

Wile E Coyote (below) has a mass of 12.5 kg and is on a hill with a height of 55 m above a valley. He wants to
reach Road Runner, who is on a hill with a height of 100 m on the other side of the valley, by using an ACME
rocket attached to some wheels. Assume that friction is negligible.
a) What is the potential energy of Wile E Coyote when he is on the 55-m ill and what would be his
potential energy if he reaches the 100-m hill?
b) What is the minimum initial speed (provided by the rocket) that would allow Wile E Coyote to reach
the other side?
c) If the initial speed of Wile E Coyote is 25 m/s, what is his speed at the bottom of the valley?
100m
55m
