Work can be calculated with the equation: Work = Force × Distance. The SI unit for work is the joule (J), or Newton. meter (N. ... One joule equals the amount of work that is done when 1 N of force moves an object over a distance of 1 m
Answer:
+300N-130N=170N
Explanation:
because two forces in opposite direction one take +and the other takes -
Heya!!
For calculate velocity, lets applicate formula

<u>Δ Being Δ</u>
d = Distance = 3790 m
t = Time = 249 s
v = Velocity = ?
⇒ Let's replace according the formula and clear "v":

⇒ Resolving

Result:
The velocity is <u>15,22 meters per second.</u>
Good Luck!!
Answer:
A body having uniform velocity has zero acceleration because
there is not change in velocity.
