Answer:
total distance is 11.3 miles
Explanation:
Given data:
distance to north = 1.2 miles
distance to south at 38 degree east of south = 6.1 miles
distance to east of north at angle 89 degree = 4 miles
distance to east of north at angle 31 degree = 6.5 miles
considering each displacement as vector so we have

total distance is 
Answer:
the work required to turn the crank at the given revolutions is 8,483.4 J
Explanation:
Given;
torque required to turn the crank, T = 4.50 N.m
number of revolutions, = 300 turns
The work required to turn the crank is given as;
W = 2πT
W = 2 x 3.142 x 4.5
W = 28.278 J
1 revolution = 28.278 J
300 revlotions = ?
= 300 x 28.278 J
= 8,483.4 J
Therefore, the work required to turn the crank at the given revolutions is 8,483.4 J
