A 20 lb weight is attached to the end of a spring. The spring is stretched 6 in. Find T/8 seconds, if the weight is the displacement from equilibrium of the weight after released from rest a point 2 inches above equilibrium position. Round to the nearest tenth of a foot. Your Answer:
A 40lb weight is attached to the end of a spring. The spring is stretched . 50 ft. Find the displacement from equillibrium of the weight after this seconds, if the weight is released from a rest point, 333ft aboux equillibrium position. Round to the nearest tenth of a foot.
Round to two decimal places if necessary. A spring is stretched 10 centimeters by a 16 N weight. The weight is then pulled down an additional 5 centimeters and released. Neglect damping. Find the function u(t) for the position of the spring at any time t. u(t) =
A 10 lb weight is attached to the end of a spring. The spring is stretched 6 in. Find the displacement from equilibrium of the weight after pi/8 seconds, if the weight is released from rest a point 6 inches above equilibrium position. Round to the nearest tenth of a foot.
MY NOTES A weight is attached to a spring suspended from a beam. At time t = 0, it is pulled down to a point 12 cm above the ground and released. After that, it bounces up and down between its minimum height of 12 cm and a maximum height of 22 cm, and its height h(t) is a sinusoidal function of time t. It first reaches a maximum height 0.8 seconds after starting. (b) What are the mean, amplitude,...
A spring is attached to the ceiling and pulled 18 cm down from equilibrium and released. After 4 seconds the amplitude has decreased to 4 cm. The spring oscillates 13 times each second. Assume that the amplitude is decreasing exponentially. Find an equation for the distance, D the end of the spring is below equilibrium in terms of seconds, t.

A spring is attached to the ceiling and pulled 13 cm down from equilibrium and released. After 3 seconds the amplitude has decreased to 9 cm. The spring oscillates 17 times each second. Assume that the amplitude is decreasing exponentially. Find an equation for the distance, D the end of the spring is below equilibrium in terms of seconds, t.
in such a way that its height, h meters after t seconds is given by the equation h.-49%28 7t +42 How Atoy rocket i launched froma 42 high plat ong will it take for the rocket to hit the ground? The toy rocket will hit the ground after approximately □ seconds Type an integer or a decimal Round to the nearest hundredth as needed)
An arrow is shot into the air and its height in feet after I seconds is given by the function f(t) = -16° + 128r. Estimate the instantaneous velocity at I = 5 seconds using difference quotients with h = 0.1, 0.01 and 0.001. If necessary, round the difference quotients to no less than six decimal places and round your final answer to the nearest integer 3x - 2 F(x) = 2 – 9x
A 16-lb weight is attached to the lower end of a coil spring suspended from the ceiling and having a spring constant of 5 lb/ft. The resistance in the spring-mass system is numerically equal to the instantaneous velocity. At t=0 the weight is set in motion from a position 1 ft below its equilibrium position by giving it an upward velocity of 1 ft/sec. Write an initial value problem that models the given situation. Write the differential equation for the...
