Similar to the previous problem, we heat about a cup (230 g) of milk (we'll treat it like water, with a specific heat of 4186 J/kg °C) from refrigerator temperature (5.2 °C) to a comfortable drinking temperature (52.5 °C) in order to make a cup of hot chocolate. First, find the energy required to heat this milk. Next, imagine giving a 1,600 kg truck this same amount of kinetic energy. What speed (in m/s) will the truck be travelling?
Question on Physics - Unit - Work and Energy A boy and a girl pull and push a crate along an icy horizontal surface, moving it 13 m at aconstant speed. The boy exerts 75N of force at an angle of 320C above the horizontal andthe girl exerts a force of 75N of force at an angle of 220C above the horizontal. Calculatethe total work done by the boy and girl together.(Hint: WT =Wb + Wg and Wb = FbΔdCosƟb and Wg = FgΔdCosƟg)
Samantha wishes to maintain her weight and goes to the gym to work off the calories she consumed at breakfast that morning. She lifts a 28.0-kg barbell from shoulder level to above her head, through a vertical height of 0.550 m. How many times must she lift the barbell to make up for the 3.25 102 Calories of energy she consumed at breakfast? Note that Calories refers to food calories. (Include lowering the barbell as well.) The answer is NOT 9

Kangaroos have very stout tendons in their legs that can be used to store energy. When a kangaroo lands on its feet, the tendons stretch, transforming kinetic energy of motion to elastic potential energy. Much of this energy can be transformed back into kinetic energy as the kangaroo takes another hop. The kangaroo’s peculiar hopping gait is not very efficient at low speeds but is quite efficient at high speeds. as shown the energy cost of human and kangaroo locomotion. The graph shows oxygen uptake (in mL/s) per kg of body mass, allowing a direct comparison between the two species. For humans, the energy used per second (i.e., power) is proportional to the speed. That is, the human curve nearly passes through the origin, so running twice as fast takes approximately twice as much power. For a hopping kangaroo, the graph of energy use has only a very small slope. In other words, the energy used per second changes very little with speed. Going faster requires very little additional…
