El soporte para un mecanismo tiene una masa de 10.2kg, soporta una carga en “D” =(1000i-1000k) N. Calcule el momento que genera la carga en “A” “B” y “C”.

A2 kg ball travellng to the right with a speed of 4 m/s collidees with a 5 kg ball traveling to the left with a speed of 3 m/s. take right to be the positive direction. what is the total momentum of the two balls before they collide? what is the total momentum of the two balls after they collide?

If a refrigerator is a heat pump that follows the first law of thermodynamics, how much heat was removed from food inside of the refrigerator if it released 380j of energy to the room?

Match each scenario to the form of energy it represents
