How much work is required to lift a 3.7-kg concrete block to a height of 2.7 m?
M g h.
g is the acceleration of gravity
M is the mass
h is the height change
is this correct 9.8*3.7*2.7=97.90
If you put a J (or Joules) after it, then yes
To calculate the work required to lift the concrete block, we will use the formula:
Work = Force × Distance
To begin, we need to determine the force required to lift the block. This force can be found using the equation:
Force = Mass × Acceleration due to gravity
The acceleration due to gravity is approximately 9.8 m/s².
Let's substitute the given values into the equation:
Force = 3.7 kg × 9.8 m/s²
Calculating this gives us:
Force = 36.26 N (rounded to two decimal places)
Now that we have the force required, we can calculate the work by multiplying it by the distance lifted:
Work = 36.26 N × 2.7 m
Calculating this gives us:
Work = 97.96 J (rounded to two decimal places)
Therefore, the work required to lift the 3.7-kg concrete block to a height of 2.7 m is approximately 97.96 Joules.
