A parcel of massmp=2.4 kg is thrown onto a stationary trolley of mass m7 = 9.9 kg, that is free to move frictionlessly on a flat, horizontal surface, as shown in the figure. T P The parcel is thrown so that when it hits the trolley it has a speed of vn = 3.1 m/s and direction given by 0 = 41° below horizontal, as shown. The parcel has a plastic collision with the trolley surface (i.e. does not bounce) and proceeds to slide along the trolley's top surface. No kinetic friction exists between the trolley surface and the parcel. The parcel slides into an undeformed linear spring of stiffness k = 1,770 N/m. What is the compression of the spring when the parcel comes to rest with respect to the trolley? 数字 单位
