What are the average acceleration and final velocity of an object which accelerates uniformly from rest, traveling a distance of 69 cm from start to finish and ending up with a velocity of 18.1 cm/sec? average velocity = (18.1 cm/sec + 0 cm/sec) / 2 average velocity = 9.05 cm/sec I found the average velocity because the velocity was not uniform. 69 cm/9.05 cn/sec = 7.62 sec I then found the time elapsed to find the acceleration. average acceleration =(18.1 cm/sec - o cm/sec)/7.62 sec average acceleration = 2.38 cm/sec/sec"" """" """" """" """" """" """" """" """" """" "
