Weight of a body on the surface of earth = ______ if $$M = mass$$ of the body

A particle is projected vertically upwards with velocity $$\displaystyle 40{ ms }^{ -1 }$$. Find the displacement and distance travelled by the particle in 6 s.
[take $$\displaystyle  g =10 m/s^{2}$$]

A body is thrown vertically upward from a point 'A' $$125 \ m$$ above the ground. It goes up to a maximum height of $$250\  m$$ above the ground and passes through 'A' on its downward journey . The velocity of the body when it is at a height of $$70\  m$$ above the ground is: ($$\displaystyle g=10\ { ms }^{ -2 }$$)
