CER: Law of Conservation of Energy Pre-Write
Students are performing a pendulum lab. The ball on the end of the
pendulum has a mass of 0.5 kg. At point A the pendulum is at the
top of its swing at 0.6 meter. At point C the potential energy is 0.6J.
Write a scientific explanation that answers the following question.
What is the velocity at point C?
(Assume the acceleration due to gravity, g, is 10 m/s2)
0.6 m

A500g object falls off a cliff and losers 100 j from its gravitational potential energy store. if the gravitational field strength g=9.8n/kg, how high is the cliff?

The number of passengers who arrive at the platform of a subway station for the 10 am train is a random variable with a mean of 120 and a variance of 16. find the lower bound of the probability that there will be between 100 and 140 passengers (round off to second decimal place).
