A 2.3 kg breadbox on a frictionless incline of angle θ = 38 ˚ is connected, by a cord that runs over a pulley, to a light spring of spring constant k = 120 N/m, as shown in the figure. The box is released from rest when the spring is unstretched. Assume that the pulley is massless and frictionless. (a) What is the speed of the box when it has moved 10.8 cm down the incline? (b) How far down the incline from its point of release does the box slide before momentarily stopping, and what are the (c) magnitude and (d) direction of the box's acceleration at the instant the box momentarily stops?

a A 2.0 kg breadbox on a incline of angle 8 = 30° is connected, by a cord that runs over a pulley, to a light spring of spring constant k = 120 N/m, as shown in the Figure 4. The coefficient of kinetic friction between box and the inclined plane is Mik = 0.52, The box is released from rest when the spring is unstretched. Assume that the pulley is massless and frictionless and the system is isolated. (a)...
An 850 kg car can roll up and down a ramp at an angle of theta = 45.0 degree to the ground. It is connected, by a massless tow rope that runs over a frictionless pulley, to a heavy spring of spring constant k = 35.0 kN/m, as shown in the figure to the right. The car handbrake is released when the car is at rest, with the spring in its unstretched state. Assume the rolling motion of the car...
