- An constant applied force of 40.1 N lifts an 2.50 kg mass straight up, resulting in a final speed of 3.6 m/s. What distance did the mass move if it was initially at rest?arrow_forwardA particle moving in the xy plane follows a path described as a function of time by i(t) = (3.4 m/s)tî - (2.8 m/s?)tj. A constant force given by F = (5.0î - 2.0j) N acts on the particle (note that other forces must act on the particle as well if it follows the path given above).
