Two students were responsible for recording the velocity of a rocket that blasted from ground zero. Student A recorded the final velocity at 4,680 ft/min. Student B was responsible for recording the initial velocity after thrust burnout which was 900 km/sec. What would be the acceleration of this rocket in m/s2, if the total amount of flight was 980 seconds? What is the acceleration from problem 1 in mph?

A car accident happened on the corner of 42nd and Grandview. A police officer measured the skid line of the truck involved. It measured to be 536 ft. A camera caught the truck stopping in 7 sec. Determine how fast the truck was traveling in miles/hr.
