caclulate the force applied to move a bag of 10kg through a vertical distance of 2.5m.if (g=10m/s) also determine the work done
if a work of 120j is done by moving a box of weight 20N through a vertical height. calculate the height
plz help I can't solve them in textbook
work=weigh*distance=10*g*2.5 Joules
force= 10g
height=work/weight=120/20 = 6 meters
I don't understand
1. F = M * g = 10 * 10 = 100 N.
Work = F * d = 100 * 2.5 = 250 Joules.
2. W = F*h.
120 = 20 * h.
h =
To calculate the force applied to move the bag of 10kg through a vertical distance of 2.5m, you can use the formula for force:
Force = mass * acceleration due to gravity
Given:
Mass (m) = 10kg
Acceleration due to gravity (g) = 10m/s^2
Vertical distance (d) = 2.5m
First, determine the force applied using the formula mentioned above:
Force = mass * acceleration due to gravity
Force = 10kg * 10m/s^2
Force = 100N
Therefore, the force applied to move the bag is 100N.
Now, to calculate the work done, you can use the formula:
Work = force * distance
Given:
Force = 100N
Distance (d) = 2.5m
Work = 100N * 2.5m
Work = 250J
Therefore, the work done to move the bag over a vertical distance of 2.5m is 250J.
For the second question, to calculate the height when a work of 120J is done by moving a box with weight 20N, you can use the formula for work done against gravity:
Work = force * distance
Given:
Work = 120J
Force = weight = 20N (weight is the force due to gravity)
Distance (d) = ?
Since the weight is acting in the vertically downward direction and the work is done against gravity, the distance is the vertical height (h).
Therefore, the formula becomes:
Work = weight * height
120J = 20N * height
To find the height (h), rearrange the formula:
height = Work / weight
height = 120J / 20N
height = 6m
So, the height through which the box is moved is 6 meters.
I hope this explanation helps you understand how to solve these problems.
