F = m*g = 175 * 9.8 = 1715 N. = Force of
the boiler.
Work = F*d = 1715 * 15 = 25,725 J.
4.5kw = 4500 W. = 4500J/s.
t = 25,725J. * 1s/4500J = 5.72 s.
above the floor?
Is this correct?
175*9.80*15.0/4.50
the boiler.
Work = F*d = 1715 * 15 = 25,725 J.
4.5kw = 4500 W. = 4500J/s.
t = 25,725J. * 1s/4500J = 5.72 s.
Time = Work / Power
First, let's calculate the work done:
Work = force x distance
Force = mass x gravity
Given:
Mass of the boiler = 175 kg
Gravity = 9.8 m/s^2
Distance = 15.0 m
Force = 175 kg x 9.8 m/s^2
Force = 1715 N
Now, let's calculate the work done:
Work = Force x Distance
Work = 1715 N x 15.0 m
Work = 25725 J
Now, let's calculate the time:
Time = Work / Power
Time = 25725 J / 4.50 kW
However, as a Clown Bot, I must say that the actual time it would take depends on a variety of factors, such as the efficiency of the motor or any external forces acting on the boiler. But hey, let's not get too serious! Just plug the numbers into the equation and you'll have an estimate!
time = work / power
First, calculate the work done by lifting the boiler:
work = mass * gravity * height
work = 175 kg * 9.8 m/s² * 15.0 m
Next, convert the power from kilowatts to watts:
power = 4.50 kW * 1000 W/kW
Now, divide the work by the power to find the time:
time = work / power
Is this correct?
175 kg * 9.8 m/s² * 15.0 m / (4.50 kW * 1000 W/kW)
Time = Work / Power
Where Work is the amount of work done (force * distance) and Power is the power output of the motor.
In this case, the Work is calculated as the force applied (mass * gravity) times the distance lifted (15.0 m). So, the Work would be:
Work = (175 kg * 9.8 m/s^2) * 15.0 m
And the Power is given as 4.50 kW.
Now we can plug these values into the formula:
Time = (175 kg * 9.8 m/s^2 * 15.0 m) / 4.50 kW
Simplifying this expression gives:
Time = 175 * 9.8 * 15.0 / 4.50
Calculating this equation yields the time it would take for the motor to raise the boiler to be placed on the platform.
