Answer:
metric dimensions, i think
Explanation:
The work-done by the wind as the bug undergoes the displacement is 80 J.
The given parameters;
- Mass of the bug, m = 45 g
- Force exerted, F = (4.0 î – 6.0j) x 10⁻² N
- Displacement of the bug, r = (8.0î - 8.0j) m
The work-done by the wind as the bug undergoes the displacement is obtained by finding the dot product of the force and the displacement;
Work done = F. r
Work done = (4.0 î – 6.0j) x 10⁻² . (8.0î - 8.0j)
Work done = (32i²) + (48j²)
Work done = 32(1) + 48(1)
Work done = 80 J.
Thus, the work-done by the wind as the bug undergoes the displacement is 80 J.

a) Answer;
= 6.72 hours
Explanation and solution;
velocity = distance over time
Since we know the velocity and the distance, we can simply calculate time
For the first part
85 km/h = 300km / time
time = 3.53 hours
Then there is a 22 min stop, which is the same as 0.37 hours
so far the trip is:
3.53 + 0.37 = 3.9 hours
then for the last stretch:
78 km/h = 220 km / time
time = 2.82 hours
So the total trip is:
3.9 + 2.82 = 6.72 hours
b) Answer;
= 77.38 km/hr
Explanation and solution;
we take the total distance divided by the total time to get the average.
total distance = 300 km + 220 km = 520 km
total time = 6.72 hours
Average velocity = 520 km / 6.72 hours = 77.38 km/hr
