Answer:
Workdone = 600 Kilojoules
Explanation:
Given the following data:
Time = 8 seconds
Power = 75,000 Watts
Distance = 58 m
To find the work done;
Power can be defined as the energy required to do work per unit time.
Mathematically, it is given by the formula;
Thus, work done is given by the formula;
Workdone = power * time
Workdone = 75000 * 8
Workdone = 600,000 = 600 KJ
Overall displacement of the object = 30 m
Average velocity = 0.6 m/s
Instantaneous velocity = 0.2 m/s
The correct graph is graph C.
<h3>What is displacement?</h3>Displacement is the distance travelled by an object in a specified direction.
Displacement is a vector quantity.
The overall displacement of the object = 40 m - 10 m
Overall displacement of the object = 30 m
Average velocity = displacement/time
Average velocity = 30 m/ 50 s
Average velocity = 0.6 m/s
Instantaneous velocity at t = 10.0 s
Instantaneous velocity = (15 - 10)/10
Instantaneous velocity = 0.2 m/s
The correct graph is graph C.
In conclusion, velocity is the change in displacement with time..
