Answer:
1. Power = 63.69 Watts.
2. Workdone = 559 Joules.
3. Force = 132.5 Newton.
Explanation:
Given the following data;
1. Force = 460N
Distance = 4.5m
Time = 32.5 seconds.
To find the power;
First of all, we would determine the work done by the student using the formula;
Workdone = force * distance
Workdone = 460 * 4.5
Workdone = 2070 Joules.
Now, we can calculate the power;
Power = workdone/time
Power = 2070/32.5
Power = 63.69 Watts.
2. Force = 215N
Distance = 2.6 m
To find the work done by the worker;
Workdone = 215 * 2.6
Workdone = 559 Joules.
3. Workdone = 318 Joules
Distance = 2.4m
To find the magnitude of force applied;
Force = workdone/distance
Force = 318/2.4
Force = 132.5 Newton.
