Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.

At time t = 0, a particle is at rest in the x-y plane at the coordinates (xo, Yo) = (9, 0) in. If the particle is then subjected to the acceleration components ax = 0.64 - 0.33t in. /sec² and ay = 0.15t - 0.03t² in. /sec², determine the coordinates of the particle position when t = 6 sec. You might consider plotting the path of the particle during this time period. Answer: (x, y) = (i " )in.

Question 15 of 20 A train has a length of 93.8 m and starts from rest with a constant acceleration at time t = 0 s. At this instant, a car just reaches the end of the train. The car is moving with a constant velocity. At a time t = 16.0s, the car just reaches the front of the train. Ultimately, however, the train pulls ahead of the car, and at time t = 36.0 s, the car is again at the rear of the train. Find the magnitudes of (a) the car's velocity and (b) the train's acceleration. (a) Number i > (b) Number i Units Units UNITS CHOICES: no units, s, m, m/s, m/s^2 L
Suppose a fly orbits you (on the horizontal plane) with a constant orbital radius of 5 meters and subject to a time-varying (tangential) acceleration given by the expression a ( t ) =1+t with an initial speed of 2 m/s. Since the fly remains a constant distance away from you, you cannot use your flyswatter the way you would like to. Suppose that you can throw your flyswatter with an initial speed of 15 m/s in any direction you want. If you throw at t=0, how, exactly, should you throw your flyswatter to hit the fly? (Give both the angle above the horizontal to throw your flyswatter –and- at what angle ahead of the fly to throw it). ..
