A car starts from rest (( v_0 = 0 )) and accelerates at ( 2 m/s^2 ) for 5 seconds. How far does it travel? Solution: ( s = 0 \cdot 5 + \frac12 \cdot 2 \cdot 5^2 = 25 ) meters.
Why does a person lean forward when a moving bus suddenly stops? Section C: Problem Solving (10 Points) A box with a mass of is lifted vertically to a height of a) Calculate the Work done to lift the box. b) What is the Potential Energy of the box at that height? Problem 2: Speed and Time A cyclist travels a) Calculate the average speed in b) Convert this speed to Answer Key C (Displacement) B ( ) — Calculation: A ( C (Watt) C (Constant) Section C Solutions 1. Work and Energy Step 1: Calculate Work Step 2: Potential Energy (Work done is equal to the change in potential energy). ✅ The Work done and the Potential Energy are both . 2.
