Question

Body falls freely from rest, a height of 2 m. if acceleration due to gravity is 10 m/ s2, determine the work done by the force of gravity​

Answer 1

Answer:

for me maths allergy I don't know answer

Answer 2

Answer:

w=20m(J)

Explanation:

i think this question is missing the mass of the body, or we can get the work done by given the mass

w(work done)=f(force)*x(distance)

as, the force which acting on the body is the gravity force ,so ($F=mg$)

where (m for mass and g for gravity $g=10m/s^2$)

so, $w=(mg)*x$

$w=(m)*10*2=20m$$(J)$

(x=h=2m)
