Answer:
The centripetal acceleration of the ball is 571.4m/s²
Explanation:
What is centripetal acceleration? Centripetal acceleration is the property of the motion of a body around a circular path. The acceleration is directed radially toward the centre of the circle and has a magnitude equal to the square of the body's speed along the curve divided by the distance from the centre of the circle to the moving body.
ac = v²/r
ac = centripetal acceleration
v = velocity
r = radius
Given data
v= 20m/s
r=0.7m
Substituting our data into the expression for centripetal acceleration we have
ac= 20²/0.7
ac=400/0.1
ac= 571.4.m/s²
