1. The number of people this planet can support is largely determined by the amount of ammonia-based fertilizer that can be produced. Without the ability to chemically manufacture ammonia, the worlds population would be closer to 1/6 of its current size. Since the early twentieth century ammonia has been produced via the process shown below.

3H2+N2>2NH3

How many grams of ammonia are produced when 30.00g of H2 react?

2. A 2200 kg car is moving at a speed of 32.0 m/s. Determine the stopping distance (in meters) if the brackes supply a force of 3500 newtons.

3. A 52 newton horizontal force pushes a 5.0 kg mass sitting on a horizontal surface. Additionally, the horizontal surface exerts a 30 newton fricitonal force on the mass. What is the acceleration of the mass?
