Answer:
IMA of given system =
Explanation:
- The "Ideal Mechanical advantage" (IMA) of given pulley is
.
- Ideal Mechanical advantage of a system is defined by the ratio of achieved or output force to the implied force. In the pulley system above, output force is the resistant force denoted by
. The input force is analogous or equivalent to the effort applied i.e.
.
- Hence by dividing these two forces we calculate the IMA of the above mentioned pulley system which is
- Its mathematical reference would be:
IMA =
Answer:
i) E = 269 [MJ] ii)v = 116 [m/s]
Explanation:
This is a problem that encompasses the work and principle of energy conservation.
In this way, we establish the equation for the principle of conservation and energy.
i)
At that point the speed 1 is equal to zero, since the maximum height achieved was 2.5 [km]. So this calculated work corresponds to the energy of the rocket.
Er = 269*10^6[J]
ii ) With the energy calculated at the previous point, we can calculate the speed developed.
