A spring with a force constant of is to be stretched from 0 to 20 cm. (a) The work required to stretch the spring from 10 cm to 20 cm is (1) more than, (2) the same as, (3) less than that required to stretch it from 0 to 10 ...A spring (spring 1) with a spring constant of is attached to a wall and connected to another weaker spring (spring 2) with a spring constant of on a horizontal surface. Then an external force of 100 N is applied to the end ...An out-of-control truck with a mass of 5000 kg is traveling at (about 80 mi/h) when it starts descending a steep (15o) incline. The incline is icy, so the coefficient of friction is only 0.30. Use the work– energy theorem ...A horizontal spring, resting on a frictionless tabletop, is stretched 15 cm from its unstretched configuration and a 1.00-kg mass is attached to it. The system is released from rest. A fraction of a second later, the spring ...A 500-g (small) mass on the end of a 1.50-m-long string is pulled aside from the vertical and shoved downward (toward the bottom of its motion) with a speed of 2.00 m/s.
