(b) The train now travels with a constant speed of 24 m/s along a straight honzontal track The total force opposing the motion due to friction and air resistance is 72 - 10^N (0) By considering the work done by the train's engine in 10s, calculate its output power powers 12]
(10) The train begins to travel up a slope Explain why the power of the train's engine must be increased to maintain the speed of 24 m/s​
