a rock is tied to the end of the string and swung in a circle with a radius of 1/2 meter. if the rock goes around once in 1/10 o
f a second what is the centripetal acceleration of the rock?
1 answer:
Answer:
1974.4328 m/s²
Explanation:
r = Radius = 0.5 m
t = Time taken = 0.1 second
Rotational speed

The centripetal acceleration is given by

The centripetal acceleration of the rock is 1974.4328 m/s²

Answer:
A×B=C×D
500×0.5=250×X
250=250×X
X=250/250=1
X=1 m
Explanation:
note: if the force plus two, the distance will be half.
The pressure of the air at the way its blowing
