Question

calculate the work done when a bag of cement 50kg is lifted through a vertical height of 4m (g=10m/s2)

Answer 1

$\huge \red { \boxed{ \boxed{ \mathsf{ \mid \ulcorner Answer : \urcorner \mid }}}}$

Mass of cement bag (m) = 50 kg

Vertical height (h) = 4 m

Gravitational Force (g) = 10 m/s²

=========================

We have formula for Work done :-

$\huge{\boxed{\boxed{\green{\sf{W \: = \: mgh}}}}}$

W = (50)(4)(10)

W = (50)(40)

W = 2000

$\huge{\boxed{\boxed{\sf{W \: = \: 2000 \: J}}}}$

•°• Work done is 2000 J
