MY NOTES PRACTICE ANOTHER As shown in the figure below, a box of mass m = 7.40 kg is sliding across a horizontal frictionless surface with an initial speed v; = 3.90 m/s when it encounters a spring of constant k = 2650 N/m. The box comes momentarily to rest after compressing the spring some amount x. Determine the final compression X (in m) of the spring. m " Tutorial MacBook Air esc 20 868 DII DD A F3 F4 F5 F6 F7 FB F10 F11 F12,_ 9. [-11 Points] SERCPWA'i'i 5.WA.037. MY NOTES 1 PRACTICE ANOTHER 'i As a 1,190 kg truck travels up a 16.5 m high hill, the nonconservatlve forces of friction and the force generated by the engine do work on the truck. If the work done by friction is -3.17 x 105 J and the work done by the l engine is +5.57 x 105 1. determine the change in the truck's kinetic energy (in id) as it travels from the bottom of the hill to the top of the hlll \\ C371 w l l .
