Aparticle a of mass 3.48 kg collides with another particle b of mass 2.51 kg. their initial velocities are u -2.23i + 0.6j and u2 0.li +0.93j just before impact. aftcr collision, they both merged and becomes a composite particle, which travel with a velocity of v 0.84 i 0.87j calculate the change in kinetic energy. give your answer to 3 decimal places. (note that if there is a loss in kinetic energy, the answer will be negative.)

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints
