A crane lifts an air conditioner to the top of a building. If the building is 12 m high, and the air conditioner has a mass of 2
Ganezh [65]

Work needed = 23,520 J

<h3> Further explanation </h3>

Given

height = 12 m

mass = 200 kg

Required

work needed by the crane

Solution

Work is the transfer of energy caused by the force acting on a moving object  

Work is the product of force with the displacement of objects.  

Can be formulated  

W = F x d  

W = Work, J, Nm  

F = Force, N  

d = distance, m  

F = m x g

Input the value :

W = mgd

W = 200 kg x 9.8 m/s²x12 m

W = 23520 J

An initially stationary object experiences an acceleration of 6 m/s2 for a time of 15 s. How far will it travel during that time
Tju [1.3M]

Answer:

675m

Explanation:

Given parameters:

Initial velocity  = 0m/s

Acceleration  = 6m/s²

Time  = 15s

Unknown:

Distance traveled by the body = ?

Solution:

To solve this problem; we use the expression;

   S = ut + \frac{1}{2}at²

 Where u is the initial velocity

              t is the time

             a is the temperature

         

Insert the parameters and solve;

  S = 0 x 15 + \frac{1}{2} x 6 x 15²  

  S = 675m
