Two students climb the ladder up the 25m high light towers at the football field. Alex weighs 80kg, but can generate {635} W of power. How long does it take Alex to climb to the top? Zeb weighs 90 kg, but can generate 750W. Does Z make it up to the top faster or slower than A? Justify your answer with calculations. While they are up at the top, Zeb finds a 5 kg bowling ball. How much potential energy does it have?

Question
- Two students climb the ladder up the 25m high light towers at the football field. Alex weighs 80kg, but can generate {635} W of power.
- How long does it take Alex to climb to the top?
- Zeb weighs 90 kg, but can generate 750W. Does Z make it up to the top faster or slower than A? Justify your answer with calculations.
- While they are up at the top, Zeb finds a 5 kg bowling ball. How much potential energy does it have?
- Zeb drops the bowling ball. Neglect air resistance. How fast is it moving when it hits the ground?
- Instead of hitting the ground, it hits a trampoline that compresses by 0.70 meters. What is the spring constant of the trampoline?
- Give TWO real world reasons why the bowling ball will not bounce all the way back up to Zeb.
- Alex finds and drops a 6 kg bowling ball. Compare the time it takes to hit the ground with the time that Zeb’s ball takes and explain.
