How much total work does a golf caddy do if he lifts a 300 N golf bag he is carrying 100 times a during a round, to a height of 1.0 m each time he lifts it?
To calculate the total work done by the golf caddy, we can use the formula:
Work = Force × Distance
In this case, the force is the weight of the golf bag, which is given as 300 N, and the distance is the height to which the golf bag is lifted each time, which is 1.0 m.
Now, to find the total work, we multiply the force and distance, and then multiply that by the number of times the golf bag is lifted during the round.
Total Work = (Force × Distance) × Number of lifts
Total Work = (300 N × 1.0 m) × 100 lifts
Total Work = 300 Nm × 100
Total Work = 30,000 Nm
Therefore, the golf caddy does a total work of 30,000 Nm during the round.
