A 1776 kg car has a speed of 10.3 m/s when it hits a tree. the tree doesn’t move and the car comes to rest. find the change in kinetic energy of the car. answer in units of j.
To Calculate the change in kinetic energy based on this formula K.E=1/2mv^2 where m is the mass=1776 kg, and v= the velocity m/s so, it should =1/2(1776kg)(10.3^2)=94208 j
