How do i find the mass of an object if it took 270 J of work to move it 15 meters?
To find the mass of an object, you can use the work formula:
Work = Force x Distance
In this case, you are given the work (270 J) and the distance (15 meters). However, you need to know the force applied to find the mass.
To calculate the force, you can use the formula:
Force = Work / Distance
Plugging in the given values, you have:
Force = 270 J / 15 m
Simplifying this, you find:
Force = 18 N
Now that you know the force applied to the object is 18 Newtons, you can use Newton's second law of motion to find the mass. The formula is:
Force = Mass x Acceleration
Since the object is not accelerating (assuming a constant velocity movement), the acceleration is 0 m/s². Thus, you have:
18 N = Mass x 0 m/s²
Simplifying this, you find:
18 N = 0 kg•m/s²
Since mass multiplied by 0 is always zero, the mass of the object is 0 kilograms.
Therefore, based on the given information, the mass of the object is 0 kg.
That depends upon the direction the object moves. Is it up?
If so, then use
W = M g H
where g is the acceleration of gravity.
