A 740 g box is pressed against a spring on a frictionless surface. The spring is compressed 7.69 cm and the box slides away at a speed of 2.15 m/s. What is the spring constant for the spring?
1.A student pushes a box initially at rest, horizontally along a frictionless surface for 10.0 m and then releases the box to continue sliding. If the student pushes with a constant 15 N force, what is the box's speed when it is released? (mass not provided) 2. If the student from the previous question hadn't pushed the box horizontally, but rather, at an angle of 54 degrees relative to the frictionless surface, what would have been the box's speed when...
General Physics Problem 4: A student pushes a baseball of m= 0.14 kg down onto the top of a vertical spring that has its lower end fixed to a table, compressing the spring a distance of d= 0.16 meters. The spring constant of the spring is k = 770 N/m. Let the gravitational potential energy be zero at the position of the baseball in the compressed spring. Randomized Variables m= 0.14 kg k= 770 N/m d= 0.16 m Part (a)...
A spring with spring constant 400 N/m is anchored at the bottom of a frictionless 30^∘ incline. A 500 g block is pressed against the spring, compressing the spring by 10 cm, then released. What is the speed with which the block is launched up the incline?
3. A student places a physics book on their outstretched palm. They then raise the book vertically upward at a constant speed. While the student is raising the book at constant speed, does the total energy of the book Earth system (kinetic plus potential) increase, decrease, or stay the same? Explain 4. An Awood machine consists of a light string draped over a low friction pulley, with a lighter mass (mi) attached to one end of the string and a...
