Answer:
B
Explanation:
Friction always eventually stops whatever is in motion.
Answer:
0.572 Hz
Explanation:
given,
length of simple pendulum, l = 0.76 m
mass of the bob, m = 365 g = 0.365 Kg
angle made from the vertical, = 12°
frequency, f = ?
f = 0.572 Hz
The frequency at which pendulum vibrates is equal to 0.572 Hz
For this case we have that the final speed is given by:
Where,
a: acceleration
vo: initial speed
t: time
Clearing the time we have:
Substituting values we have:
it takes 4.375 s for the car to stop
