A mass weighing 20 pounds stretches a spring 6 inches. The mass is initially released from rest from a point 8 inches below the equilibrium position. (a) Find the position x of the mass at the times t = ?/12, ?/8, ?/6, ?/4, and 9?/32 s. (Use g = 32 ft/s2 for the acceleration due to gravity.)
Consider a spring mass system with a 144 lb object attached. Suppose the object stretches the spring 18 inches in equilibrium. If the object is initially displaced 8 inches above equilibrium and given an initial velocity of -2 ft/s, find its displacement y in feet as a function of time t. Assume that this motion is undamped and that the spring is not deformed in the process. y(t) = feet

A mass weighing 16 pounds stretches a spring feet. The mass is initially released from rest from a point 4 feet below the equilibrium position, and the subsequent motion takes place in a medium that offers a 1 damping force that is numerically equal to - the instantaneous velocity. Find the equation of motion x(t) if the mass is driven by an external force equal to f(t) = 20 cos(3t). (Use g = 32 ft/s? for the acceleration due to gravity.) x(t) = ft
Consider a spring-mass system with damping y and without any external forces acting on the system. A 0.5 kg object stretches the spring 0.2 m by itself. The gravitational acceleration is g≈ 10 m/s². a. Let y(t), measured positive in the downward direction, denote the displacement of the mass from its equilibrium position at time t. Write the equation of motion of the object and find the value y for which the motion is critically damped. b. Find the displacement y if the motion is critically damped and the initial conditions are y(0) = 0.1 and y'(0) = ³√√/2. c. What will happen to the solution for t→∞0?
An object stretches a spring one foot in equilibrium. Suppose the object is displaced 2 inches above equilibrium and given an initial downward velocity of 4v2 inches per second. Assuming there is no damping, find a formula for the object's displacement, for t> 0.
A mass weighing 4 pounds is attached to a spring whose constant is 2 Ib/ft. The medium offers a damping force that is numerically equal to the instantaneous velocity. The mass is initially released from a point 1 foot above the equilibrium position with a downward velocity of 16 ft/s. Determine the time (in s) at which the mass passes through the equilibrium position. (Useg = 32 ft/s? for the acceleration due to gravity.) Find the time (in s) after the mass passes through the equilibrium position at which the mass attains its extreme displacement from the equilibrium position. What is the position (in ft) of the mass at this instant? ft
Please help solve. I keep getting it wrong.
A toy rocket is launched vertically upwards from the ground. After 5.5 seconds it begins to fall downwards. Model the rocket as a particle and assume that it moves under the influence of gravity alone. Take the magnitude of the acceleration due to gravity to be g = 9.8 m s−2 . Give numerical answers to two significant figures. (a) Calculate the initial speed of the rocket, and the maximum height above the ground that it reaches (b) Sketch a graph of the velocity v (in metres per second) of the rocket against the time t (in seconds), from the time at which the rocket is launched until the time it begins to fall downwards.
