Answer:
The time taken for the airplane to cover the distance is 15 minutes.
Explanation:
Given;
velocity of airplane, u = 800 km/h
distance traveled by the airplane, s = 200 km
The time of this motion is given by;
s = ut + ¹/₂at²
at constant velocity, acceleration, a = 0
s = ut
t = s / u
t = (200 km) / (800 km/h)
t = 0.25 hour = 15 mins
Therefore, the time taken for the airplane to cover the distance is 15 minutes.
The force advantage of the direction changing pulley shown is 1. The correct option is b.
<h3>What is force advantage?</h3>
Force is the mechanical physical quantity. The force advantage is equivalent to the mechanical advantage equal to the ratio of output to the input force.
In the single fixed pulley, there is only one rope segment that pulls up on the load, so,
The force advantage is
F.A = 50 N / 50 N = 1
Thus, the force advantage of the direction changing pulley shown is 1. The correct option is b.
