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:
vₓ = 6.73 m/s
Explanation:
- Assuming no other external influences than gravity, in the horizontal direction (which we make to coincide with the x- axis) , speed is constant, so, applying the definition of average velocity, we can write the following equation:
- Now, in the vertical direction (coincident with the y- axis) , as both movements are independent each other, initial velocity is zero, so we can write the following equation for the vertical displacement:
- where Δh = -37.0 m , g = -9.8 m/s2
- Solving (2) for t, we get:
- Taking t₀ = 0, ⇒ Δt = t
- Replacing (3) in (1), we get:
- As the horizontal velocity is constant, the initial horizontal velocity is just the average one, i.e., 6.73 m/s.
