Complete Question:
A horizontal force of 5N is required to maintain a velocity of 2m/s for a block of 10kg mass sliding over a rough horizontal surface. The work done by this force in one minute is:
Answer:
Workdone = 600 Joules.
Explanation:
Given the following data;
Force = 5N
Velocity = 2 m/s
Time = 1 minute to seconds = 60 seconds.
Mass = 10 kg
To find the work done;
First of all, we would determine the distance covered by the block.
Distance = speed * time
Distance = 2 * 60
Distance = 120 seconds
Mathematically, workdone is given by the formula;
[tex] Workdone = force * distance[/tex]
Substituting into the formula, we have;
[tex] Workdone = 5 * 120 [/tex]
Workdone = 600 Joules.
Therefore, the work done by this force in one minute is 600 Joules.
