2. Given the mass of the car plus rocket, use the change in momentum to calculate the change in speed. Formula: momentum = p = mass x velocity. 66720kg m/s = 1653kg (AV) 66720 = AV 1653 AV = 40. 3630 m/s Mass of car in kilograms 1588 kg Mass of rocket in kilograms 65 kg Total mass of car and rocket in kilograms 1653 kg Change in speed of car (in m/s) 40.4 m/ s 3. Convert this speed from meters/ second to MPH. Then add this to the alleged initial speed when the rocket was fired (assume 50 MPH). Change in speed of car (in MPH) 90.32 mph Final speed of car after adding initial speed 140.32 mph Step-by-Step: 1 mph = 0.44 meter/sec 90.32 mph = 40.38 meter/sec Initial speed = 50 mph Final speed = 50 + 90.32 = 140.32 mph 4. In the field below, discuss one other potentially questionable claim of the original story as reported in the e-mail that might be tested by applying laws of physics. The claim that the car reached speeds in excess of 350 MPH
