Transcribed Image Text:Solve the following problem. Show your complete solution.
1. In the event of tug-of-war, the CAS team pulls the SHS team by applying a force of
1500 N to the rope between them. How much work does CAS team do to SHS team if
they pull them to a distance of 1.8 m towards them?
2. How much work is done against the gravity in lifting 5 kg. box of school supplies
through a vertical distance of 1.5 m?
(Note: Work is also done if you lift an object: W = F,Sy, where the applied force is equal to the weight of
the object: F, = weight and since Weight = mg, therefore, work done when lifting an object is W = mgs,
where m is mass, g is acceleration due to gravity and s is distance/height.)
3. A 50 kg boy wanted to get a coconut from the tree. Find the work done by the boy if:
a. He climbs the tree with a height of 6.0 m;
b. He uses a ladder with length 12.0 m and inclined 30° with the horizontal.
4. Convert the following:
a. 220 W =
kW
b. 1.5 hp =
C. 6.5 kW =
hp
