Solve. The trains on the Behemoth start at rest from at the loading platform (10 m above the ground) and are lifted to the top of the first hill by a motor in 67 s. At the top, 70.1 m above the ground, the train has a speed of 1.7 m/s. Along the way, the train experiences a frictional force of 3724 N. The train (including passengers) has a mass of 2700 kg. How powerful should the motor be to accomplish this task? Complete the energy diagram and bar chart below. System earth, train, wheels.

ERNES B: Back to the Behemoth 1. Solve. The trains on the Behemoth start at rest from at the loading platform (10 m above the ground) and are lifted to the top of the first hill by a motor in 67 s. At the top, 70.1 m above the ground, the train has a speed of 1.7 m/s. Along the way, the train experiences a frictional force of 3724 N. The train (including passengers) has a mass of 2700 kg. How powerful should the motor be to accomplish this task? Complete the energy diagram and bar chart below. System = earth, train, wheels. E + Ez + Enz Work-energy equation: 1-2 Tanin wheel Farth C: He's Got the Power 1. A Powerful Run. Usain Bolt is able to reach a top speed of 44.72 km/h by the 65-m mark of a 106-m race. it took time about 6.3 seconds to reach that top speed. He has a mass of 96 kg, He accomplishes this by transferring energy shared ins chemicals in his muscles into energy of motion. We will explore this using two models. (a) Model #1: 100% Efficient. Let's begin by assuming that all the energy used by Boit is transferred to kinetic energy. Draw an energy bar chart showing the transfer of energy What is his power while he is accelerating to his top speed? (b) Model #2: Thermal Losses. Unfortunately, chart above suggests. Quite a bit of energy show Let's assume that his muscles are 50% kinetic energy. Draw the bar chart for this
