A squirrel runs at a steady rate of 0.51 m/s in a circular path around a tree. If the squirrel's centripetal acceleration is 0.4
3 m/s2, what is the radius of the circle?
0.60 m
1.2 m
0.36 m
0.84 m
2 answers:
By definition, the centripetal acceleration is given by:

Where,
v: tangential speed
r: radius of the circular path
Clearing the radio we have:

Substituting values we have:

Therefore, the radius of the circular path is equal to 0.60 meters.
Answer:
The radius of the circle is:
0.60 m
option1
I googled it and I think the answer is 0.60m
good luck!

Throw it sideways and try to make it spin around but it needs to be thrown high up then it should kinda glide down
Answer:
The strength of gravity decreases.
An example of that would be if you were in space; you float around because there's no gravity.
Answer:
14009. 72 kgms^-1
Explanation:
Momentum is the product of an objects mass and velocity
Energy is the capacity to do some type of work
Average speed = total distance / time ⇒ total distance = average speed * time
Average speed = 270 km / p hours
distance = d
hours = x
d = 270/p * x
