Sagot :
The kinetic energy of the train is for the given mass and speed is 9.832 MJ.
The given parameters;
- mass of the train, m = 2.1 x 10⁶ kg
- height, h = 578 m
- distance traveled, s = 54 km
- average speed, v = 11 km/h = 3.06 m/s
The kinetic energy of the train is calculated as follows;
K.E = ¹/₂mv²
where;
- m is the mass of the train
- v is the speed of the train
The kinetic energy is calculated as;
[tex]K.E = \frac{1}{2} \times (2.1\times 10^6) \times 3.06^2\\\\K.E = 9.832 \times 10^6 J\\\\K.E = 9.832 \ MJ[/tex]
Thus, the kinetic energy of the train is for the given mass and speed is 9.832 MJ.
