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.

Question

Q2. A roller coaster car starts from rest at A and moves down the curved rail. The
roller coaster car has mass of 880 kg and has a speed that increases at a = (6.0 -
0.04 s) m/s, where s (in m) is the distance traveled from point A along the curved
rail. At this instant the car has traveled s = 10 m, at which point x = 15 m. g 9.81
m/s. (Hint, along the tangential direction, the 3 basic kinematics equations apply for
s, v and a)
(2) Determine the radius of curvature, p. Your answer must include 2 places after the
decimal point, and proper unit.

A box is moving in the i direction with a constant acceleration. A mass, suspended from the top of the box by a linear spring (unstretched length of zero), is moving to the right as well and isn't moving with respect to the box (the spring isn't changing in length and θ is constant). The force exerted by the spring on the mass is given by its spring constant k times its extension. For the present case, the spring is extended 5 cm from its rest length, k = 30 N/m and m = 0.15 kg. What is the angle θ equal to, and what is the acceleration of the box? You can solve for this without using the computer
At a certain point in the reentry of the space shuttle into the earth's atmosphere, the total acceleration of the shuttle may be represented by two components. One component is the gravitational acceleration g = 9.56 m/s2 at this altitude. The second component equals 11.25 m/s² due to atmospheric resistance and is directed opposite to the velocity. The shuttle is at an altitude of 47.9 km and has reduced its orbital velocity of 28300 km/h to 14750 km/h in the direction = 1.88°. For this instant, calculate the radius of curvature of the path and the rate i at which the speed is changing. Answers: p= i = i FU km m/s²
At a certain point in the reentry of the space shuttle into the earth's atmosphere, the total acceleration of the shuttle may be represented by two components. One component is the gravitational acceleration g = 9.67 m/s² at this altitude. The second component equals 10.66 m/s² due to atmospheric resistance and is directed opposite to the velocity. The shuttle is at an altitude of 49.6 km and has reduced its orbital velocity of 28300 km/h to 16160 km/h in the direction = 1.23°. For this instant, calculate the radius of curvature of the path and the rate i at which the speed is changing. Answers: p= i = i i km m/s²
The y-coordinate of a particle in curvilinear motion is given by y = 8.3t3 - 5.4t, where y is in inches andt is in seconds. Also, the particle has an acceleration in the x-direction given by ax = 10.6t in./sec?. If the velocity of the particle in the x-direction is 13.0 in./sec when t = 0, calculate the magnitudes of the velocity v and acceleration a of the particle when t = 1.7 sec. Construct v and a in your solution. %3D Answers: When t = 1.7 sec, V = i in./sec a = in./sec2

Your answer is partially correct. The velocity of a particle moving in the x-y plane is given by (7.70i + 4.91j) m/s at time t = 7.38 s. Its average acceleration during the next 0.029 s is (3.3i + 2.6j) m/s?. Determine the velocity v of the particle at t = 7.409 s and the angle 8 between the average- acceleration vector and the velocity vector at t = 7.409 s. Answers: v = ( 7.7957 i+ 4.9754 j) m/s 5.73
