A pair of sleds weighs 25kg and experiences a frictional force of 25N. If a dog team applies a 175N force pulling it 12m.
1. Find the work done by friction
2. Find the work done by the dog team
3. Find the net work done
I need to compare my answers so the could you please post the correct answers?
1. W = Fk*d 25 * 12 Joules.
2. W = 175 * 12 Joules.
3. Wn = (175*12)-(25*12)
Sure, here you go:
1. The work done by friction can be calculated using the formula: Work = Force x Distance. In this case, the frictional force is 25N, and the distance is 12m. So, the work done by friction is 25N x 12m = 300 J (joules).
2. The work done by the dog team is also calculated using the formula: Work = Force x Distance. The force applied by the dog team is 175N, and the distance is 12m. So, the work done by the dog team is 175N x 12m = 2100 J.
3. The net work done is the total work done by all the forces acting on the sleds. To find the net work done, you need to find the sum of the works done by friction and the dog team. So, the net work done is 300 J + 2100 J = 2400 J.
Hope this helps!
Sure! Here are the correct answers:
1. To find the work done by friction, we use the formula W = F * d, where W is the work done, F is the force, and d is the distance. In this case, the force of friction is 25N and the distance is 12m. Therefore, the work done by friction is 25N * 12m = 300J.
2. To find the work done by the dog team, we again use the formula W = F * d. The force applied by the dog team is 175N and the distance is 12m. So, the work done by the dog team is 175N * 12m = 2100J.
3. To find the net work done, we subtract the work done by friction from the work done by the dog team. Therefore, the net work done is 2100J - 300J = 1800J.
I hope this helps!
To find the work done in each scenario, we can use the formula:
Work = Force x Distance
1. Work done by friction:
Given: Frictional force = 25N, Distance = unknown
To find the distance, we need to use the equation:
Frictional force = (Coefficient of friction) x (Normal force)
From the given information, we cannot directly determine the coefficient of friction or the normal force. Therefore, we can't find the work done by friction without more information.
2. Work done by the dog team:
Given: Force applied by the dog team = 175N, Distance = 12m
To find the work done by the dog team, we can use the formula:
Work = Force x Distance
Work = 175N x 12m = 2100 Joules
3. Net work done:
The net work done is the sum of the work done by all forces acting on the sled.
Net Work = Work by dog team - Work by friction
In this case, due to the lack of information regarding the frictional force's distance, we cannot accurately calculate the net work done.
Therefore, the only answer we can provide is the work done by the dog team, which is 2100 Joules.
