The total displacement of the object is 30 m. The total work done by the object is 450J. What was the total Force of the object? a. What is the acceleration of the object which has a mass of 10 kg? b. What is the final velocity of the object? c. How long did it take? 1 Name: ______________________________________ Date: ____________________________________ Education Is Freedom! AP PHYSICS 1 AP Physics Reteach CW 2. The total work done by an object was -500J. This objects initial velocity was 15 m/s traveling for 50 m. What is the total Force of the object? a. What is the acceleration of the object which has a mass of 20 kg? b. What is the final velocity of the object? c. How long did it take? 2 Name: ______________________________________ Date: ____________________________________ AP PHYSICS 1 AP Physics Reteach Education Is Freedom! CW You are given the following variables, calculate the work this object does! t = 10 s vi = 0 m/s d = 100 m θ = 0 degrees m = 20 kg vf = 15 m/s The work you calculated is the Non-Conservative Work, solve for the height using the Conservation of energy Equation. 3 Name: ______________________________________ Date: ____________________________________ Education Is Freedom!
