Answer:
56,643.36m/s²
Explanation:
Centripetal acceleration is expressed as shown:
a = v²/r
v is the velocity
r is the radius
If the length of the sling is 90cm, hence the circumference of the circular path is 90cm
Since C = 2πr
0.9 = 2πr
r = 0.9/2π
r = 0.9/2(3.14)
r = 0.9/6.28
r = 0.143m
Get the centripetal acceleration:
a = 90²/0.143
a = 56,643.36m/s²
Hence the the centripetal acceleration of the stone is 56,643.36m/s²
