course Phy 201 Week 2 Quiz 1If an object increases velocity at a uniform rate from 5 m/s to 21 m/s in 12 seconds, what is its acceleration and how far does it travel? Sketch a velocity vs. clock time graph for an object whose initial velocity is 5 m/s and whose velocity 12 seconds later is 21 m/s. Explain what the slope of the graph means and why, and also what the area means and why. Change in velocity = 21m/s – 5 m/s = 16m/s Acceleration = change in velocity/’dt = (16m/s)/12s = 1.3 m/s ‘ds = 21cm/s * 12s = 252cm
