Answer : The correct option is, (d) 1080 J
Explanation :
Total energy = Kinetic energy + Potential energy

where,
m = mass of an object = 2.0 kg
v = speed of an object = 10 m/s
h = height of an object = 50 m
g = acceleration due to gravity = 
Now put all the given values in the above expression, we get:

Total energy = 1080 J
Thus, the total energy will be, 1080 J
