EXERCISE 1.2 In physics, energy E carries dimensions of mass times length squared divided by time squared. Use dimensional analysis to derive a relationship for energy in terms of mass m and speed v, up to a constant of proportionality. Set the speed equal to c, the speed of light, and the constant of proportionality equal to 1 to get the most famous equation in physics. (Note, however, that the first relationship is associated with energy of motion, and the second with energy of mass. See Chapter 26.) ANSWER E= kmv² - E= mc? when k = 1 and v = c.

Provide your calculations, including all relevant steps are included and your units are labeled. The plane carrying the supplies will be cruising at a constant velocity of 250 miles per hour relative to the ground and at a height of 2,650 meters above the target site. Using this information, create a supply drop plan including all required information and calculations outlined below. As you are completing your supply drop plan, remember that correct SI units are a required component of your calculations and descriptions. A) Provide your calculations, including all relevant steps are included and your units are labeled. B) Describe the components of the kinematics equations used in your initial calculations below.

Consider the following kinematics equation: V²₁ = V² + 2ax where Vf and V are both representative of velocities with units of [m/s], determine the proper units of 2a4x (the second term on the right-hand-side of the equals sign), such that the equation obeys the principle of dimensional homogeneity. (Include square brackets around your final answer). Typo NO
