A pickup truck of mass 3500 kg moving at 72 kmh-1 collides head-on with a car of mass 2000 kg moving in the opposite direction. After colliding, both the pickup and the car came to rest. (i) An 8 grade physics student commented that the law of conservation of momentum was NOT upheld in this collision, since both vehicles were moving before the collision and none of them was moving after colliding. State whether or not you agree with the student's comment and give a reason why you agree or disagree.

Nacidified solution was electrolyzed using copper electrodes. a constant current of 1.18 a caused the anode to lose 0.584 g after 1.52 ✕ 103 s. given that the charge of an electron is 1.6022 ✕ 10−19 c, calculate avogadro's number. assume that copper is oxidized to cu2+ ions.

Two steel balls, each of mass m, are welded to a light rod of length l and negligible mass and are initially at rest on a smooth horizontal surface. a horizontal force of magnitude f is suddenly applied to the rod as shown. determine (a) the instantaneous acceleration a of the mass center g and (b) the corresponding rate at which the angular velocity of the assembly about g is changing with time.
