Given mass = 2kg, height = 10m,g = 9.8.
We know that Work done W = FD
= > W = (mg)(D)
= > W = (2 * 9.8)(10)
= > W = 196 Joules.
Hope this helps!
The mass of the box is 8.5 kg.
<h3>What is mass?</h3>
Mass can be defined as the quantity of matter contained in a body.
To calculate the mass of the box, we use the formula
Formula:
- F = mgμ............. Equation 1
Where:
- F = Force
- m = mass of the box
- g = acceleration due to gravity
- μ = coefficient of friction
Make m the subject of the equation
- m = F/gμ..................... Equation 2
From the question,
Given:
- F = 25 N
- g = 9.8 m/s²
- μ = 0.3
Substitute these values into equation 2
- m = 25/(0.3×9.8)
- m = 25/2.94
- m = 8.5 kg
Hence, the mass of the box is 8.5 kg.
