Calculate the Instantaneous Velocity of a particle traveling along a straight line for time t = 3s with a function x = 5t^2 + 2t + 3?
A person walks 750 m due north, then 250m due east. If the entire walk takes 12 minutes, find the person's average velocity.
An object moves along a straight line. First it travels at a velocity of 12 m / s for 5s and then continues at the same direction with 20m/s for 3s. What is its average speed?
