WebMar 12, 2024 · Solution: The k of the spring is 20 N/m. Δx is 25 cm. We need this unit to match the unit in the spring constant, so convert the distance to meters. Δx = 25 cm = 0.25 m. Plug these values into the Hooke’s Law formula. Since we’re looking for the force required to pull the spring apart, we don’t need the minus sign. F = k·Δx. WebNov 5, 2024 · You release the object from rest at the spring’s original rest length. (a) Show that the spring exerts an upward force of 2.00 m g on the object at its lowest point. (b) If the spring has a force constant of 10.0 N / m and a 0.25-kg-mass object is set in motion as described, find the amplitude of the oscillations.
