Work Done by Force of Gravity

A particle of...

Question

A particle of mass $100$ g is throws vertically upwards with a speed of $5$ m/s. The work done by the force of gravity during the time the particle goes up is?

Solution

Work done =f•s
m=100g
v=5m/s
force=mass×acceleration
0.1×(-g)=-1N
since acceleration is constant s0 $v^{2} - u^{2} = 2 a s$
25=2(-g)s
s=1.25
now work done=-1N×1.25m
