A boat weighing 1.5 tons, starting off, for some time reaches a speed of v = 5 m / s (assume that the boat is moving in calm water). The traction force of the motor is constant and equal to F = 103 Assuming that the drag force Ffr to the boat’s movement is proportional to the speed (Ffr = k⋅v, where the friction coefficient is k = 100 kg / s), determine the time for which the boat reaches the specified speed.

Question

A boat weighing 1.5 tons, starting off, for some time reaches a speed of v = 5 m / s (assume that the boat is moving in calm water). The traction force of the motor is constant and equal to F = 10³ Assuming that the drag force F_fr to the boat’s movement is proportional to the speed (F_fr = k⋅v, where the friction coefficient is k = 100 kg / s), determine the time for which the boat reaches the specified speed.
