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.
