What is A 0.25 kg stone tied to a 0.5 m string whirls at a speed of 4 m s What is the centripetal acceleration acting on the stone?

Centripetal acceleration = V2/R = (4)2/(0.5) = 32 meters/sec2
The centripetal acceleration doesn't depend on the stone's mass.
(The centripetal force does.)
The centripetal acceleration doesn't "act on" the stone.
(The centripetal force does.)
The centripetal force acting on the stone is F = M A = (0.25) (32) = 8 newtons.

An athlete whirls a 6.63 kg hammer tied to the end of a 1.4 m chain in a horizontal circle. The hammer moves at the rate of 1.6 revs. What is the centripetal acceleration of the hammer?
The centripetal acceleration of the hammer can be calculated using the formula a = v^2 / r, where v is the tangential velocity and r is the radius of the circle. Given that the hammer moves at 1.6 revs (1 rev = 2π rad) and the radius is 1.4 m, we can find the velocity using v = 2π * 1.4 m * 1.6 revs = 14.08 m/s. Plugging these values into the formula, we get a = (14.08 m/s)^2 / 1.4 m = 140.8 m/s^2.
