A train of mass 7.510^5kg accelerates from rest at constant rate along straight, horizontal track. It reaches a speed of 24m/s in 60s. Now the total force opposing the motion due to friction and air resistance is 7.210^4 N . Calculate
1) resultant force acting on the train before it achieves constant speed
2) trains output power at constant speed
