15.3.11
A body of mass m = 100 kg begins to move from a state of rest along a horizontal rough plane under the action of a constant force F. After a path equal to 5 m, the velocity of the body becomes 5 m / s. Determine the modulus of force F if the sliding friction force Fmp = 20 N. (Response 270)
