A box of mass m is pressed against (but is not attached to) an ideal spring of force constant k and negligible mass, compressing the spring a distance x. After i is released the box slides up a frictionless incline as shown in the figure and eventually stops. If we repeat this experiment with a box of mass 2m A) the lighter box will go twice as high up the incline as the heavier box. B) both boxes will have the same...
A box of mass m is pressed against (but is not attached to) an ideal spring of force constant k and negligible mass, compressing the spring a distance x. After it is released, the box slides up a frictionless incline as shown in the figure and eventually stops. If we repeat this experiment but instead use a spring having force constant 2k k m Smooth 0000000 Smooth O all other choices are correct O just as it moves free of...
A box of mass m is pressed against (but is not attached to) an ideal spring of force constant k and negligible mass, compressing the spring a distance x. After it is released, the box slides up a frictionless incline as shown in the figure and eventually stops. If we repeat this experiment but instead compress the spring a distance of 2x.
A 3.5 kg mass is pressed against a spring of spring constant 90.0 N/m, compressing it 25.0 cm. Find the greatest amount of kinetic energy this mass could gain after it is released.
A jack-in-the-box with a box of mass M and clown of mass m = 285.0 g rests on a horizontal table (see figure below). The clown is attached to the box by means of a lightweight, vertical spring with force constant k = 1.00 ✕ 102 N/m. Zara pushes down on the clown with an additional force of 5mg, further compressing the spring. When Zara removes her hand, the clown jumps upward, and the spring lifts the box off the...
1. Two identical 0.800-kg masses are pressed against opposite ends of a light spring of force constant 1.75 N/cm, compressing the spring by 11.0 cm from its normal length.Part AFind the speed of each mass when it has moved free of the spring on a frictionless, horizontal table.Express your answer with the appropriate units.2. A 15.0 kg fish swimming at 1.40 m/s suddenly gobbles up a 4.50 kg fish that is initially stationary. Neglect any drag effects of the water.Part...
A toy car of mass 0.620 kg is pressed against a spring. The spring constant is 250 N/m and the spring is compressed a distance of 0.031 m. How fast is the cart moving after it's released from the spring? Ignore the effects of friction.
A mass of 65.0 g is attached to the spring. A spring ( = 1700 N/m) is stretched to a distance A - 1.00 m and released U kx E = K + U K Part A. When the mass gets to a position of x 0.450 m. What is it's velocity? O 457 m/s to the night 200x109 m/s to the O 144 m/s to the left 72.8 m/s to the right
A spring of mass of 5 kg is resting on a frictionless horizontal surface and is pressed against a spring with a spring constant of 500 N/m, compressing the spring 25 cm and then released. Draw a picture, label the variables, and label applicable equations to answer the following: (a) How fast will the spring be going at x = + .25 m?; (b) how fast will the spring be going at x = 0 m?; (c) at what position...
A box with a mass of 1.80 kg slides along a flat track with friction until it makes contact with a horiztonally mounted spring. At the instant that the box makes contact with the spring the box has a velocity magnitude of 2.00 m/s. The box slides and slows down until it comes to a rest after compressing the spring 11.0 centimeters. If the coeficient of kinetic friction between the track and box is 0.56, what is the spring constant...
