A mass m = 1.4 kg hangs at the end of a vertical spring whose top end is fixed to the ceiling. The spring has spring constant k = 75 N/m and negligible mass. At time t = 0 the mass is released from rest at a distance d = 0.35 m below its equilibrium height and undergoes simple harmonic motion with its position given as a function of time by y(t) = A cos(ωt – φ). The positive y-axis...

You throw a tennis ball North with an initial speed of 24 feet per second, at an angle of elevation 30° above horizontal, releasing the ball 4 feet above the ground. A steady wind imparts a constant acceleration of 3 feet per second squared Eastward. Acceleration due to gravity is a constant 32 feet per second squared downward. Throughout the problem, let East be the positive x direction, North the positive y direction, and up the positive z direction. Let...
