A mass of 0.5 kg moving along a horizontal frictionless surface encounters a spring having k = 200 N/m. The mass compresses the spring by 0.1 meters before reversing its direction. Consider the total time the mass is in contact with the spring. What is the total impulse delivered to the mass by the spring? (Let the initial direction of the mass's motion be the positive direction.)

a 2.0 kg mass moves along a frictionless horizontal surface at a speed of 5.0 m/s. The mass encounters a 30 degree inclined surface with a constant friction force of 1.5 N. At 1 m high (vertical) the surface levels off and is again frictionless. the mass then encounters a spring with k=10 N/m a) how far is the spring compressed after the mass comes to rest? b) how far down the inclined plane will the mass move after bouncing...

A horizontal mass-spring system consists of a 2 kg mass moving on a frictionless surface attached to a spring. The other end of the spring is attached to a wall. The mass is pulled and released. The resultant simple harmonic motion has a period of 5 s and it is observed that the maximum velocity of the mass is 0.3 m/s. a) Calculate the spring constant of the spring. (b) Calculate the amplitude of the motion. Sometime later, when the...

Problem 1 A block of mass m is sliding on a frictionless, horizontal surface, with a velocity vi . It hits an ideal spring, of spring constant k, which is attached to the wall. The spring compresses until the block momentarily stops, and then starts expanding again, so the block ultimately bounces off (see Example 5.6.2). (a) Write down an equation of motion (a function x(t)) for the block, which is valid for as long as it is in contact...
