1.	A car and a truck have the same kinetic energies at a certain instant while they are moving along two parallel roads.If the mass of turck is 100 times greater than that of the car, find the ratio of velocity of the truck to that of the car .
Answer» SOLUTION :`1/2mv_c^2=1/2(100M)v_t^2` `v_t^2/v_c^2=1/100` `v_t/v_c=1/10`
