Answer:
The answer to your question is: Ke = 3000 Joules
Explanation:
Data
mass = 15 kg
speed = 20 m/s
Kinetic energy = ?
Equation
Ke = 3000 Joules
Answer:
,
Explanation:
First we build the Free Body Diagram (please see first image for further details) associated with the mass, we notice that system consist of a three forces that form a right triangle (please see second image for further details): (i) The weight of the mass, (ii) two tensions.
The requested tension and angle can be found by the following trigonometrical and geometrical expressions:
(1)
(2)
Where:
- Weight of the mass, measured in newtons.
,
- Tensions from the mass, measured in newtons.
If we know that and
, then the requested values are, respectively:
