Answer:
Explanation:
As the sum of the two right directed forces match exactly the left directed force, the only unbalanced force, and thus the net force, is the upward 25 N force.
Answer:
Explanation:
Given:
Mass of the boat, m = 4040 kg
The driving force of engine, FB = 4660 N in west = + 4660 N
The force of wind, Fwi = 880 N in east = -880 N
The force of water, Fwa = 1400 N in east = -1400N
Total three forces are acting on the boat
Fnet= Fb+fwi+Fwa
Fnet= 4660 - 880 - 1400
Fnet= +2380N
Acceleration (a) = Force/mass
= 2380/4040
= 0.59m/s2
