- Answer both or NONE Question1 - For exercise, an athlete lifts a barbell that weighs 400 N from the ground to a height of 2.20 m at a constant speed in a time of 1.60 s. What is the metabolic energy, in kJ (kiloJoule)? Your answer needs to have 3 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement. Question2 - For exercise, an athlete lifts a barbell that weighs 400 N from the ground to a height of 2.20 m at a constant speed in a time of 1.60 s. How much thermal energy is created in this process, in kJ (kiloJoule)? Your answer needs to have 3 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.arrow_forward1. Refer to figure 1. The 10.0 kg green cart travels down a ramp - from point A to B. Calculate its starting potential energy, kinetic energy at the bottom of the ramp, and its velocity coming off the bottom of the ramp. If the cart coasts from points B to C, did it do any work? How far up the 2nd ramp does the cart go as measured from the ground? 10.0m Figure 1 Barrow_forwardsolve correctly. I will rate accordingly.arrow_forward
- 1. A roller-coaster car with a mass of 1200 kg starts at rest from a point 20 m above the ground. At point B, it is 9 m above the ground. [Express your answers in kilojoules (kJ).] a. What is the initial potential energy of the car? b. What is the potential energy at point B? c. If the initial kinetic energy was zero and the work done against friction between the starting point and point B is 40 000 J (40 kJ), what is the kinetic energy of the car at point B 2. The time required for one complete cycle of a mass oscillating at the end of a spring is 0.80 s. What is the frequency of oscillation?arrow_forwardPlease help me with this question: 1. Bob a man with a mass of 90kg, climbs up a 3.5m high tree. a.) How much work must Bob do in order to make it to the top of the tree, assuming that he begins and ends at rest? Bob now jumps out of the tree and land on the ground. b.) How fast will he be going just before he hits the ground? c.) First assume that he forgets to bend his knees. That means that he wil land hard - the cushions on his feet will make him move downward 1.6cm while coming to a stop, but that's it. How much force will he feel from the ground while he stops? d.) As you can see, that enormous force result in a everely injured Bob. So rewind, and let's assum Bob bends his knees this time. That means that the ground forced is in contact with him while he moves 0.45cm downward. Now how much force will the ground exert on Bob?arrow_forwardA shopper pushes a cart 20.0 m at a constant speed across a level floor in a grocery store, against a 35.0 N frictional force. The shopper pushes in a direction 25o below the horizontal. A.) What is the work done on the cart by friction? B.) What is the force the shopper exerts on the cart? C.) If the cart is moving at 0.750 m/s, then how much power does the shopper have to exert on the cart?arrow_forward
