(6) Given that,
Force in east direction = 67 N
Force in west direction = 82 N
Solution,
According to the given figure,
Two forces are acting in opposite direction. Maximum force is acting in west direction. It means the net force is acting in west direction.
Net force = 82-67
= 15 N (Due west)
The forces are unbalanced. It is because the magnitude of force in west is more than in east.
Net force = 15 N, Direction of motion = West and the forces are unbalanced.

Answer:
time required is 6.72 years
Explanation:
Given data
mass m = 3.20 ✕ 10^7 kg
height h = 2.00 km = 2 × 10^3 m
power p = 2.96 kW =2.96 × 10^3 J/s
to find out
time period
solution
we know work is mass × gravity force × height
and power is work / time
so we say that power = mass gravity force × height / time
now put all value and find time period
power = mass × gravity force × height / time
2.96 × 10^3 = 3.20 ✕ 10^7 × 9.81× 2 × 10^3 / time
time = 62.784 × 10^10 / 2.96 × 10^3
time = 21.21081081 × 10^7 sec
time = 58.91891892 × 10^3 hours
time = 6.72 years
so time required is 6.72 years
