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 12 kg block is pressed against a spring with spring constant k = 1424 N/m. The spring is normally 65 cm long but the block is pressed against it to compress the spring until it is only 27 cm long. The block is then released and the spring pushes it forward onto a frictionless surface. a)How fast is the block moving immediately after it leaves the spring? b) The mass then slides across a 2.5 m wide surface with...
A 2.80-kg box is sliding along a frictionless horizontal surface with a speed of 1.8 m/s when it encounters a spring.
A 2.80-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 of the spring, if the box compresses the spring 5.50 cm before coming to rest. b. Determine the initial speed the box would need in order to compress the spring by 1.30 cm. A box slides from rest down a frictionless ramp inclined at 39.0° with respect to the horizontal and is stopped at the bottom of...

A block of mass 100.0 g rests on a frictionless, horizontal plane. It is pressed firmly against a horizontal spring with spring constant 2000.0 N/m (assume that the spring is massless). The object is held in position such that the spring is compressed 1.00 cm shorter than its undisturbed length. If the block is suddenly released, at what speed will it be traveling when it is free of the spring?
