Name Date hr 4.3 Acceleration Acceleration is the rate of change in velocity of an object. To determine the acceleration, you use the formula below. The units for acceleration are meters per second per second or m/s. (Final velocity - intial velocity) Acceleration = time (v - v a = The acceleration formula can be rearranged to solve for other variables such as final velocity (v) and time (t). ID + la = la ('a - la) a. 1) A skater increases her velocity from 2.0m/s to 10.0m/s in 3.0seconds. What is the skater's acceleration? Given Unknown Equation Substitution Solution 2) A car accelerates at a rate of 3.0m/s'. If the original velocity is 8.0m/s, how many seconds will it take for the car to reach a final velocity of 25.0m/s? Equation Given Unknown Substitution Solution 3) A car slows down from 24 m/s to 15 m/s in 12 seconds. What is the driver's acceleration? Equation Substitution Solution Given Unknown 4) A car traveling at a speed of 30 m/s encounters an emergency and comes to a complete stop. How long will it take for the car to stop if the acceleration is -4. Om/s'? Substitution Solution Given Unknown Equation
