- An unstretched spring hanging to the ceiling is connected to an object. The object is released and drops a distance of 11.8m before it stops, and the mass of the object is 0.6kg. What is the spring constant? The mass of the string is irrelevant.A crane lifts a 268 kg crate a height of 12.4 m in a time of 80.0 s at a constant speed. What is the crane's power?

A 640.0 g box is then placed against the spring and then released. After travelling 3.15 m from the release point, the speed of the mass is 5.68 m/s. The coefficient of friction is 0.34. What is the spring constant of the spring?

How much time does it take for the block to travel to the point x=1.5m? answer in secondsA mass resting on a horizontal, frictionless surface is attached to one end of a spring; the other end is fixed to a wall. It takes 3.1 J of work to compress the spring by 0.15 m . If the spring is compressed, and the mass is released from rest, it experiences a maximum acceleration of 12 m/s2. Find the value of the spring constant. Find the value of the mass.
- a) A friend says they have a spring that stretches 5cm every 1 N that is applied. If they stretch the spring to 10 cm (double the distance), how does the spring constant change? b) If given 2 springs, how can you tell which has a greater spring constant without takinG measurements?A 2.8 kg box is sliding along a frictionless horizontal surface with a speed of 1.8 m/s when it encounters a spring, (a) Determine the force constant (in N/m) of the spring, if the box compresses the spring 7.5 cm before coming to rest. N/m (b) Determine the initial speed (in m/s) the box would need in order to compress the spring by 1.4 cm. m/s Additional Materials9. A 7.9 kg object is suspended 10 m above the ground. Directly beneath it is a spring with a spring constant of 6500 N/m. Qualitatively describe what occurs to the energy of the system once the object is released? (Hint: Consider what occurs as the object falls, encounters the spring, and if it will go back up again!)
