Question

A wheel of radius 0.23 m, which is moving initially at 25.0 m/s, rolls to a stop in 246.0 m. The wheel's rotational inertia is 0.170 kg·m2 about its central axis. Calculate the magnitude of its linear acceleration.

Answer 1

Answer: -1.27 m/s^2

Step-by-step explanation:

a = - V^2 / 2x

a = -(25^2) / 2 x (246) = 1.27 m/ s^2

Therefore the linear acceleration of the wheel is - 1.27 m/s^2
