Answer:
It is always less than 1 because the load arm is always longer than effort arm.
Explanation:
In the formula, MA= effort divided by load which makes it less than 1.
This helps by reducing the applied force(effort). It is a speed multiplier.
Hope it helps.
The last choice is your answer, I just did it.
Answer:
4.408 m.
Explanation:
Given:
m = 72.1 kg
vf = 9.3 m/s
vi = 0m/s
a = 9.81 m/s^2
Equations of motion:
i. vf = vi + a*t
ii. S = vi*t + 1/2*(a*(t^2))
iii. vf^2 = vi^2 + 2a*S
Using iii. equation of motion;
(9.3)^2 = 0 + 2 * (9.8) * S
S = 86.49/19.62
= 4.408 m.
