Consider what elements are part of a vector.
True or False: Average velocity can be negative.
Think about direction on a number line.
An object moves along a straight line with its position given by s(t) = 2t² + 3t. Find the instantaneous velocity at t = 4 seconds.
Use calculus to differentiate the position function.
A cyclist rides at a speed of 12 m/s for 2 minutes and then at 8 m/s for 1 minute. Calculate the average velocity for the entire trip.
