Question

Ashish's mother carried two suitcases of total weight 200N to three stairs at a height of 10m and then pushes it with a constant speed to a distance of 35m by applying a horizontal force of 50N. How much work does Ashish's mother do on the suitcases during the entire motion?

Answer 1

Work = mgh + FS
= (200 N × 3 × 10 m) + (50 N × 35 m)
= 7750 Joule
= 7.75 kJ

Ashish’s mother did work of 7.75 kJ

Answer 2

Work = mgh + FS

= (200 N × 3 × 10 m) + (50 N × 35 m)

= 7750 Joule

= 7.75 kJ
