No, only average speed can be calculated from the distance of 90 meters and the time 3 seconds hope this helps

Answer:
velocity = distance / time
Explanation:
To solve this problem it is necessary to apply the concepts related to the Period based on the length of its rope and gravity, mathematically it can be expressed as

g = Gravity
L = Length
T = Period
Re-arrange to find the gravity we have

Our values are given as

Replacing we have



Therefore the correct answer is C.
The particle has an acceleration vector with one component directed toward the center of its orbit, and the other directing tangentially to its orbit. Call these components
(
for center) and
(
for tangent). Then its acceleration vector has magnitude

We have

where
is the particle's speed and
is the radius of orbit, so

We're given that the particle's speed changes at a rate of 23.1 m/s^2. Its velocity vector points in the same direction as
, i.e. perpendicular to
, so

Then the magnitude of the particle's acceleration is
