Question

a body of mass 6 kg is moved along a horizontal frictionless surface through a distance of 7m and then moved up vertically 5 metre total work done is

Answer 1

Work = mgh (m= mass, g=gravitational force, h= height)

Since, In horizontal there are not any forces acting on the body. So the work done by forces in Horizontal is 0. So, we will consider only vertical case.

W = F x d
=> W = 0 x 7
=> W = 0
