Answer:
speed and acceleration of the turbine V = 80.24 m/s and a = 109.1 m/s²
Explanation:
The wind turbine describes a circular motion, with constant angular velocity, we can find the speed with the equation
V = x / t
Where x is the distance traveled which is the length of the circle (X = 2πr) and time is the time in a revolution, which in this case is called the period
t = 60/13
t = 4.62 s
x = 2 p1 59
x = 370.71 m
V = 370.1 / 4.62
V = 80.24 m / s
The centripetal acceleration is given by the equation
a = V² / r
a = 80.24²/59
a = 109.1 m / s²
The second part of the exercise seems totally independent
The dog r = 16cm with a speed of 2.5 m/s, ask us the centripetal force
F = m a
F = m (v² / r)
m = 10 mg (1g / 1000mg) 1 Kg / 1000 g) = 1 10⁻⁵ Kg
r = 16 cm (1m / 100cm) = 16 10⁻² m
F = 1 10⁻⁵ 2.5²/16 10⁻²
F = 3.91 10⁻² N
Let's calculate the relationship between the force and the weight of the drop
F / W = 3.91 10⁻² (1 10⁻⁵ 9.8)
F / W = 3.99 10
²
See that the force of the shake is approximately 400 times greater than the weight of the drop
Answer:
The mass is inversely proportional to the acceleration so the acceleration a1 is twice that acceleration a2
Explanation:
The force of friction and the kinetic force make the law of mass in moving so
The forces are the same however at the moment to determinate the acceleration
are constant because they make the same motion however the difference of mass make the acceleration difference
