A spring scale reads 39.2 N when the object is hung vertically at rest. The object and spring scale are now swung in a vertical circle. Predict what the spring scale will read at the bottom of the circle if the object is moving at a speed of 6 m/s at that point and the radius of the circle is 1.200 m.

A spring is hung vertically from a fixed support. When an object of mass m is attached to the end of the spring, it stretches by a distance y. When an object of mass of 2m is hung from the spring, it stretches by a distance 2y. A second, identical spring is then attached to the free end of the first spring. If the object of mass 2m is attached to the bottom of the second spring, how far will...

An object is hung on a vertical spring originally at rest and set to start bobbing up and down by releasing it from rest at the spring’s original rest length. (a) What force acts on the object (in terms of its weight) when it is at its lowest point? (b) Suppose the object weighs 250 g and the spring’s spring constant is 10.0 N/m. Calculate the amplitude of oscillations. (c) Determine the maximum speed of the object. Thank you in...

4. When a solid object is suspended from a spring scale in air the scale reads 21.7N. The object is then completely submerged in water and the spring scale reads 16.6N. Draw a free-body diagram for the object suspended from the scale in air. You may ignore the very small buoyant force from the air. Using a Newton's 2 nd law equation for the vertical direction on your FBD determine the mass of the object. Draw a free-body diagram for...
