If urmila weighing 85 kg climbs up a staircase having vertical height of 5 m 10 times baby how many calories does she born in a week one calorie is equal to 4.18 J

Hello Lilly Mary Mathew dear, to climb up once through height 5 m with mass 85 kg is given by m g h
Here g = 10 m/s^2 for convenience
So 85 * 10 * 5 J
Then daily 10 times. So daily energy needed 10* 85 * 10 * 5 J
In one week required energy = 7 * 10 * 85 * 10 * 5 J
Now to convert J into calorie we have to divide J by 4.18 
Hence 71172 cal
