If the spring constant of the bumper is 3.80 × 106 N/m, what is the maximum compression of the spring during the collision? … WebA 1.40-kg object is held 1.25 m above a relaxed, massless vertical spring with a force constant of 300 N/m. The object is dropped onto the spring. (a) How far does the object compress the spring? Your response differs from the correct answer by more than 10%.
Spring Constant (Hooke
Web22 jul. 2024 · The initial gravitational potential energy of the object is: where. m = 1.50 kg is the mass of the object. g = 9.8 m/s^2 is the acceleration of gravity. h = 1.27 m is the height of the object. The final elastic potential energy of the compressed spring is. where. k = 300 N/m is the spring constant. x is the compression of the spring WebAnswer (1 of 2): I’ll assume that the 3.6m is the distance from the mass’s starting point to the top of the spring, and that the mass is initially stationary and just falls under gravity. Call x the distance the spring is compressed. So the mass drops through a … bryanston weather today
Conservation of energy and a spring Physics Forums
Web[What happens when a spring is stretched too far?] Equations Hooke’s law The force required to stretch an elastic object such as a metal spring is directly proportional to the extension of the spring for small distances. The force exerted back by the spring is known as Hooke's law \vec F_s= -k \vec x F s = −kx WebThe second approach gives the compression when the velocity of the object is zero. When the block falls on the spring, it oscillates between x = 2 m g k and x = 0. Since the spring is ideal and the air resistance is negligible, this oscillation does not die down and so the question is wrong. WebTranscribed Image Text: A 1.40-kg object is held 1.15 m above a relaxed, massless vertical spring with a force constant of 340 N/m. The object is dropped onto the spring. (a) How far does the object compress the spring? m (b) Repeat part (a), but this time assume a constant air-resistance force of 0.600 N acts on the object during its motion. examples of the word cliche
