Question

A person of mass 50 kg climbs a tower of height 72 m calculate the W.D. (Taken9=9.8ms^2​

Answer 1

Answer:

38250J

Explanation:

mass=50 kg

height= 72m

acceleration or gravity= 9.8 or –9.8 m/s²

force is –490 N

work done = –490* 72

= –35,280 J

Answer 2

Given ,

Mass = 50kg

Height = 72m

g = 9.8 m/s²

To Find :-

The work done

Formula :-

Work done = m × g × h

where, m is the mass of the body, g is the acceleration due to gravity and h is the height.

On inserting the values in the formula

We get ,

Work done = 50kg × 9.8m/s² × 72m

$=\: {\dfrac{50 \times 98 \times 72}{10}}$

= 35280

Therefore, work done = 35280 J
