1. You need to have 6,000 Joules of kinetic energy to knock down a building with a wrecking ball. Use the
graphs to determine the combinations of mass and speed that will give you 6,000 joules of energy.

When would a bouncy ball have the most potential energy

Nitrogen dioxide decomposes according to the reaction 2 no2(g) ⇌ 2 no(g) + o2(g) where kp = 4.48 × 10−13 at a certain temperature. if 0.70 atm of no2 is added to a container and allowed to come to equilibrium, what are the equilibrium partial pressures of no(g) and o2(g)
