Answer:
T₂ = 1937.68 N
Explanation:
First, we will calculate the weight of the object:
Now, we will calculate the resultant tension in the ropes. Since the ropes are perpendicular. Therefore,
where,
T = Resultant Tension
T₁ = Tension in rope 1
T₂ = Tension in rope 2
According to the given condition tension in the first rope is 2.2 times the tension in the second rope:
T₁ = 2.2 T₂
Therefore
Now, the weight of the object must be equal to the resultant tension for equilibrium:
<u>T₂ = 1937.68 N</u>
Answer:
time required to mow lawn is 1274.06 minutes
Explanation:
given data
average mow = 1400 square meters each hour
area = 320000 square feet
to find out
How many minutes will take to mow lawn
solution
we know that here 1 square feet is equal to 0.092903 square meter
so 320000 square feet will be = 0.09203 × 320000 = 29728.9728 square meter
so time required is express as
time required =
time required =
time required = 21.23 hours
so time required = 21.23 × 60 min = 1274.06
time required to mow lawn is 1274.06 minutes
Answer:
15.88m/s
Explanation:
At the top of the roller coaster you will have three forces acting on the roller-coaster. See the image below. Fc is the centripetal force (for an object in circular motion), Fg is the gravitational force, and Fn is the normal force. To achieve the minimum speed we assume the roller-coaster is barely touching the vertical loop and so the normal force is zero. This leaves two acting forces.
