A truck and car have the same speed of 30m/s. If their masses are in the ratio 1:3 find the ratio of its kinetic energy..please Reply fast ..I have my exams tomorrow.. (Sorry for bothering)
Let their masses be x and 3x.. and velocity be v
K.E of car(1) = 1/2 * x * v2 [ v2 - vsquare ]
K.E of car(2) = 1/2 * 3x * v2 [ " " ]
==> Ratio = 1 : 3 ...
Hope this helps you!!
