1. Using variables, derive an equation for the range of the launched projectile in terms of the origin (specify its location), launch height, muzzle velocity and the acceleration due to gravity. (I.e., do step B.4.) You may attach separate paper if necessary.

2. You have measured a rectangular surface with sides of length21.5 0.2cm and width of8.7 0.3cm . What is the perimeter and area of this surface? Be explicit with your error calculations. I.e., state the formula for perimeter and area and the error calculations for each, then substitute the given values.
