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.

A particle which moves with curvilinear motion has coordinates in millimeters which vary with the time t in seconds according to x = 2.4t2 - 6.9t and y = 3.2t2 - t/2.2. Determine the magnitudes of the velocity v and acceleration a and the angles which these vectors make with the x-axis when t = 2.9 s. Answers: When t = 2.9 s, V = i mm/s, e, = a = i mm/s?, O = i
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.
The x- and y-motions of guides A and B with right-angle slots control the curvilinear motion of the connecting pin P, which slides in both slots. For a short interval, the motions are governed by x = 12 +0.55t² and y = 16-0.57t³, where x and y are in millimeters and tis in seconds. Calculate the magnitudes of the velocity v and acceleration a of the pin for t = 2.5 s. Sketch the direction of the path and indicate its curvature for this instant.

When the effect of aerodynamic drag is included, the y-acceleration of a baseball moving vertically upward is au = -g - kv², while the acceleration when the ball is moving downward is ad = -g + kv², where k is a positive constant and v is the speed in feet per second. If the ball is thrown upward at 94 ft/sec from essentially ground level, compute its maximum height h and its speed vf (a positive number) upon impact with the ground. Take k to be 0.0017 ft¹ and assume that g is constant. au=-g-ku² y 1 194 ft/sec Answers: h = Vf= i i ad=-g+kv2 h ft ft/sec
A particle which moves with curvilinear motion has coordinates in millimeters which vary with the time t in seconds according to x = 4.5t2 - 3.8t and y = 4.1t2 - t3/3.5. Determine the magnitudes of the velocity v and acceleration a and the angles which these vectors make with the x-axis when t = 4.2 s.
At time t = 12 s, the velocity of a particle moving in the x-y plane is v=0.08i + 2.28j m/s. By time t = 12.12 s, its velocity has become -0.08i + 2.14j m/s. Determine the magnitude day of its average acceleration during this interval and the angle 0 made by the average acceleration with the positive x-axis. The angle is measured counterclockwise from the positive x-axis. Answers: dav 0= Mi i m/s² O
