Answer:
The maximum number of passengers that can ride in the elevator are n°= 28 passengers.
Explanation:
P= 40 HP = 29840 W
d= 20m
t= 16s
me= 600kg
mp= 65 kg
g= 9.8 m/s²
v= d/t
v= 1.25 m/s
P=F*v
P/v= F
F= 23872 N
m= F/g
m= 2435.91 kg
m= me + n° * mp
(m - me) / mp = n°
n°≅ 28 passengers
Answer:
-0.8 m/s²
Explanation:
Acceleration is the slope of a velocity vs. time graph.
a = Δv / Δt
a = (0 m/s − 12 m/s) / (15 s − 0 s)
a = -0.8 m/s²
Answer:
Explanation:
For the simple pendulum problem we need to remember that:
,
where is the angular position, t is time, g is the gravity, and L is the length of the pendulum. We also need to remember that there is a relationship between the angular frequency and the length of the pendulum:
,
where is the angular frequency.
There is also an equation that relates the oscillation period and the angular frequeny:
,
where T is the oscillation period. Now, we can easily solve for L:
