Question

A person of mass 50kg climbs a tower of height 72metres . Calculate the work done(g=9.8ms-2)

Answer 1

Answer:

35,280 J

Explanation:

Given,

Mass (m) = 50kg

Acceleration (a or g) = 9.8m/s²

Displacement (s) = 72m

We know,

Work Done = Force × Displacement

= F × S

= m×a×s

= 50×9.8×72

= 35,280 joules
