Final answer:
The centripetal acceleration experienced by a 5kg ball being pushed around a circle with a radius of 0.5 m and a tangential speed of 3.2 m/s is 20.48 m/s².
Step-by-step explanation:
To calculate the centripetal acceleration experienced by the ball, the formula for centripetal acceleration ac = v2/r can be used, where v is the tangential speed and r is the radius of the circle. Here, the tangential speed v is given as 3.2 m/s, and the radius r is 0.5 m. Plugging these values into the formula gives us ac = (3.2 m/s)2 / (0.5 m) = 20.48 m/s2. Therefore, the ball experiences a centripetal acceleration of 20.48 m/s2.
