A 50-kg object moves along the inclined plane under the tension I=(300+150√1)N (where t is in seconds) of the motor device. The coefficient of kinetic friction between the object and the inclined plane is 4 = 0.4. If the velocity of the object is v₁ = 2m/s when t=0, its velocity is_ m/s when t=2s. (Express the answer to three significant figures and g-9.81m/s²) my's
