Answer:
The centripetal acceleration of the ball swung at constant speed is, a = 7.2 m/s²
Explanation:
Given data,
The speed of the ball, v = 3 m/s
The length of the string, r = 1.25 m
The centripetal acceleration of the ball swung at constant speed is given by the formula,
a = v²/ r
= 3² / 1.25
= 7.2 m/s²
Hence, the centripetal acceleration of the ball swung at constant speed is, a = 7.2 m/s²
