Answer:
The correct answer to the following question will be "41.87 m".
Explanation:
The given values are:
The speed of trooper =
The velocity of red car =
Now,
A red car goes as far as possible until the speed or velocity of the troops is the same as that of of the red car at
(∵
)
then,
The distance covered by trooper,
The distance covered by red car,
=
=
Maximum distance =
=
Answer:
F = 32.28 N
Explanation:
For this exercise we must use the rotational equilibrium relation
Σ τ = 0
In the initial configuration it is in equilibrium, for which all the torque and forces are compensated. By the time the payment lands on the bar, we assume that the counter-clockwise turns are positive.
W_bird L / 2 - F_left 0.595 - F_right 0.595 = 0
we assume that the magnitude of the forces applied by the hands is the same
F_left = F_right = F
W_bird L / 2 - 2 F 0.595 = 0
F =
we calculate
F = 0.560 9.8 14.0 /2.38
F = 32.28 N
