Answer:19.6 N9.8 JExplanation:Question 1:Given;

a counterweight of mass, m = 2-kg

distance moved by this weight, d = 0.5 meters

the gravitational force of the counterweight is calculated as;

F = mg

where;

F is gravitational force

m is the mass

g is acceleration due to gravity

F = 2 x 9.8 =

19.6 NThus, the gravitational force of the counterweight is

19.6 NQuestion 2:Given;

a counterweight of mass, m = 2-kg

height moved by this weight, h = 0.5 meters

the work done is calculated as;

Work done = Force x distance moved by this weight

Work done = 19.6 x 0.5 =

9.8 JThus

,the work done is9.8 J
