Please help! 1. If a soldier lifts a 2-kg counterweight 0.5 meters, what is the gravitational force of the counterweight? (Include the equation and appropriate units.)

2. If a soldier lifts a 2-kg counterweight 0.5 meters, how much work is done? (Include the equation and appropriate units.)

please please please please help!!!

Explanation:

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 N

Thus, the gravitational force of the counterweight is 19.6 N

Question 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 J

Thus, the work done is 9.8 J

car a and b are moving in opposite directions

plz mark.me the brainliest i rlly need this kind of yours in exchange

well, you would divide 135 by 33 to get your answer. then that is how many seconds it would take. boardman should fly about 132 m or 4.090909090909091 seconds.
