brutus, a champion weightlifter, raises 240 kg a distance of 2.35 m. How much work is done by Brutus lifting the weights?
W=Fs
W=mgs
W=240kgx10m/s²x2.35m
W=5640J
To find the work done by Brutus while lifting the weights, you can use the formula:
Work = Force × Distance
In this case, the force exerted by Brutus while lifting the weights is equal to the weight being lifted, which is 240 kg. The distance over which the weights are lifted is given as 2.35 m.
So the work done by Brutus can be calculated as:
Work = 240 kg × 2.35 m
Now, multiply the weight (240 kg) by the distance (2.35 m) to find the work done:
Work = 564 kg·m
Therefore, the work done by Brutus lifting the weights is 564 kg·m.
To calculate the work done by Brutus in lifting the weights, you can use the formula:
Work = Force × Distance
In this case, the force is the weight being lifted, and the distance is the height it is lifted. Given that Brutus lifts 240 kg a distance of 2.35 m, we can substitute these values into the formula:
Work = 240 kg × 9.8 m/s^2 × 2.35 m
Here, we multiply the weight (240 kg) by the acceleration due to gravity (9.8 m/s^2) to get the force. The resulting force is then multiplied by the vertical distance (2.35 m) the weight is lifted.
Now, let's calculate the work:
Work = 240 kg × 9.8 m/s^2 × 2.35 m
Work = 5652 J
Therefore, Brutus does 5652 Joules of work in lifting the weights.
