Problem

The velocity of a bike is 2 m/s at t=0t = 0 s, 6 m/s at t=2t = 2 s and 10 m/s at t=4t = 4 s. What can you conclude about its acceleration during the 4 s interval? (a) Non-uniform acceleration because the acceleration changes with time (b) Uniform acceleration of 4 m/s24\ \text{m/s}^2 (c) Uniform acceleration of 2 m/s22\ \text{m/s}^2 (d) Uniform acceleration of 2.5 m/s22.5\ \text{m/s}^2
