A physics lab demonstrates the principles of simple harmonic motion (SHM) by using a spring affixed to a horizontal support. The student is asked to find the spring constant, k. After suspending a mass of 255.0 g from the spring, the student notices the spring is displaced by 33.5 cm from equilibrium. With this information, calculate the spring constant.
An 8.5- {rm kg} point mass and a 15- {rm kg} point mass are held in place 50- {rm cm} apart. A particle of mass m is released from a point between the two masses 19- {rm cm} from the 8.5-{rm kg} mass along the line connecting two fixed masses.
A 2200 kg sport utility vehicle travelling at 86 km/h can be stopped in 0.15 s if it hits a concrete wall. Presume a 60 kg person was in the car that hit this wall. The velocity of the person equals that of car both before and after the crash, and..
