- A 10 kg box experiences a force of 15 Newtons in the positive x-direction and 8 Newtons in the negative y-direction. What is the magnitude of the net force acting on the box? Answer in Newtons.A train locomotive pulls a train with a mass of 1.10 ✕ 10^7kg on level rails. The locomotive exerts a constant force of 6.90 ✕ 10^5N on the train. How much time does it take to increase the speed of the train from rest to 64.0 km/h? (Ignore any resistance force from the rails on the wheels of the train. Enter your answer in minutes.)Two forces É, = (81.24i – 26.83j) N and É, = (27.41i - 80.52j) N are exerted on a particle. The particle's mass is 23.21 kg.
