1. write the 4 formulas that represent motion with uniform acceleration describing what each variable represents 2. The following graph represents the movement of an object as a function of time. Sections I, II, Ill and IV were identified; From this graph calculate: 12- 10 8 -(1) - V [m/s] (III) 8 12 16 20 Time [s] a) The acceleration between 0 s and 4 s (0 m/s^2) b) The speed between O s and 4 s (10 m/s) c) The distance traveled between 0 s and 4 s (40 m) d) The acceleration between 4 s and 8 s (-0.5 m/s^2) e) The acceleration between 16 s and 20 s (1.5 m/s^2) f) In which sections is the acceleration zero? 3. Which graph represents the 2nd part of Exp 2 when the cart was pushed down the inclined track as shown in the figure below? And describe what happens to the velocity on the graph O
