Let’s assume that Taran can spin the 2.2 kg cup in a perfect horizontal circle, and his arm length plus cup length is 1.3 meters. If he can spin it around in 0.75 seconds, how much tension is in his arm? Numerical answers only

Abatter hits a 0.140-kg baseball that was approaching him at 30 m/s and, as a result, the ball leaves the bat at 40 m/s in the reverse of its original direction. the ball remains in contact with the bat for 2.0 ms. what is the magnitude of the average force exerted by the bat on the ball?
