Acceleration 2

if a car traveling at a velocity of 80 m/s/south accelerated to a velocity of 100 m/s east in 5 seconds, what is the cars acceleration? using Pythagorean theorem

Correct result:

a =  25.6125 m/s2

Solution:

v1=80 m/s v2=100 m/s v=v12+v22=802+1002=20 41 m/s128.0625 m/s t=5 s a=v/t=128.0625/5=4 41=25.6125 m/s2



We would be pleased if you find an error in the word problem, spelling mistakes, or inaccuracies and send it to us. Thank you!
