1. The ID motion of an object is described by the equation: x(v) =(2.00)t^3-t^2-(3.00)t+1 , in m on the i direction.
a. Find the instantaneous velocity and acceleration equations.
b. How far from the origin is the object 1.50 s later?
c. What is the average velocity of the object, in the first two seconds?
d. How much distance has the object travelled between the first and third second of the trip?
e. What is the displacement from the origin at 3.00 s time?
2. You want to throw a ball up to land on a ledge 6.00 m above you (look at the schematic below.)
a. Write the position and velocity equations that apply, indicating proper vertical directions.
b. If the ball is to just reach the ledge, what is the initial velocity you need lo throw it with?
c. How much time will it take?
d. If you misjudge and throw the ball with an initial velocity of 15.0 m/s, how high will it climb?
e. How fast is the ball going to be travelling at the height of the ledge?
