Abaseball bat could be considered a uniform rod. it ha a mass of 0.97 kg and a length of 97 cm. if a player accelerates it from rest to 2.8 rev/s in 0.20s, how much torque is applied?

The torque is 26.75 N-m.

Explanation:

Given that,

Mass = 0.97 kg

Length = 97 cm

Time = 0.20 s

Angular speed

We need to calculate the moment of inertia of rod at one end

Using formula of the moment of inertia

Put the value into the formula

We need to calculate the angular acceleration

Using formula of angular acceleration

Put the value into the formula

We need to calculate the torque

Using formula of torque

Put the value into the formula

Hence, The torque is 26.75 N-m.

whichever one it is, it's definitely not one that you included on the list you provided.
