An ant rotates its mandible, of length 1.30 mm and mass 130 μg (which we can model as a uniform rod rotated about its end), at a high angular speed. as the tip strikes the ground, it undergoes an angular acceleration of 3.5×108rad/s2.

The force on the trip is .

Explanation:

Given that,

Length = 1.30 mm

Mass = 130 μg

Angular acceleration

If we assume that the tip of the mandible hits perpendicular to the ground, what is the force on the tip

We need to calculate the torque

Using formula of torque

Put the value of torque and moment of inertia into the formula

Put the value into the formula

Hence, The force on the trip is .
