Calculate the power of an engine which can pull a mass of 500 metric t

1.	Calculate the power of an engine which can pull a mass of 500 metric ton up an incline rising 1 in 100 with a velocity of 10 m/s.
Answer» Solution :`sin theta = (1)/(100)`, Velocity = 10 m/s , Mass m = 500 metric ton `= 500 XX 10^(3)` kg F = Force applied , `= 500 xx 10^(3) xx 9.8 xx (1)/(100) = 49 xx 10^(3)` N Power `P = F upsilon = 49 xx 10^(3) xx 10 = 49 xx 10^(4)` watts = 490 kw.
