Answer only No. 1

Activity 2: PROBLEM SOLVING Directions: Solve the following problems 1. The x-coordinates of an object at time t = 1.00 s and t = 4.00 s are 3 00 m and 5.00 m respectively. Calculate the average velocity of the object on the time interval t = 1.00 s to 4.00 s. Construct and interpret the position-time graph, velocity-time graph and acceleration-time graph. 2. Suppose that the velocity of an object at time t seconds is 3t2- Vt +3+ 2. At t = 0, the position of the object is 7m. What is the position of the object 8 seconds later? 3. A particle moves in a straight line with its position given by the following equation: x(t) = 4-4t3+212 + 3t +6. a. Find its position after 1 second. b. Find its velocity after 2 seconds. 4. Calculation of the instantaneous velocity at a specific time, given x as a function of time: The position of an object is x(t) = 1.00 + 2.00 t- 3.002, where x is in meters and t is in seconds. Calculate the instantaneous velocity of the object at time t =3.00 s.
