An object attached to an ideal massless spring is pulled across a frictionless surface. If the spring constant is 45 N/m and the spring is stretched by 0.88 m when the object is accelerating at 2.0 m/s², what is the mass of the object?

Question

The force exerted by the spring is given by F = -kx, where k is the spring constant and x is the displacement from the equilibrium position. The acceleration of the object is given by a = F/m, where m is the mass of the object. Substituting the given values into these equations, we get:-45 N/m * 0.88 m = m * 2.0 m/s^2m = 20 kg
