1. Imagine going outside on a cold day without a jacket. Explain your body’s homeostatic control system response to this in terms of the four components: the sensor mechanism, the control center, the effector mechanism, and the feedback control loop.

Velocity is a description of both speed and direction, therefore it - a vector - a force arrow - the same as acceleration - a magnitude

The 10-kg double wheel with radius of gyration of 125mm about o is connected to the spring of stiffness k = 600 n/m by a cord which is wrapped securely around the inner hub. if the wheel is released from rest on the incline with the spring stretched 225 mm, calculate the maximum velocity v of its center o during the ensuing motion. the wheel rolls without slipping
