An object travels a distance of 32 cm in 17.6 seconds from start to finish. If its acceleration is uniform and its initial velocity zero, then what are its average velocity,
acceleration and final velocity?
v_ave= 'ds/'dt = (s_2-s_1) / (t_2 - t_1) = 32 cm / 17.6 seconds = 1.82 cm/s
v_f = 1.82 cm/s * 2 = 3.64 cm/s
acceleration = cm/s^2 = v_f / t = (3.64 cm/s) / 17.6 s = 0.207 cm/s^2"
&#Very good responses. Let me know if you have questions. &#
