Answer:
Explanation:
Given in the question
= Angular frequency = 31 rad/s
Now,
The required function is
Answer:
a = 1.16 m/s²
Explanation:
In order to find the acceleration of the ball we will use 3rd equation of motion.
2as = Vf² - Vi²
where,
a = acceleration = ?
s = displacement = 21.9 m
Vf = Final Velocity = 7.14 m/s
Vi = Initial Velocity = 0 m/s (Since, ball starts from rest)
Therefore, using the values, we get:
2a(21.9 m) = (7.14 m/s)² - (0 m/s)²
a = (50.97 m²/s²)/(43.8 m)
<u>a = 1.16 m/s²</u>
In SI units with dry air at 20*C (68*F), the speed of sound c is 343 meters per second (m/s).
The answers is 343 meters per second:
for sure thermometers and pryometers as I just learned and did some search ing. so these are. two classes of the heat measure measurement s! your welcomes!!
you can probably find out more of this and other stuff on here for more information scientificamerican
4 km in 30 min then 8 km in 60min or an hr. so 8km/hr.
