Question: Let u, v, and w be distinct vectors of a real vector space V . [6 marks] (a). Show that span{u, v, w}=span{u + v − w, u + w − v, v + w − Answer: To show that ( \text{span}{u, v, w} = \text{span}{u + v – w, u + w – v, v + w – u} ), we need...

The curvilinear motion of a particle is defined by v, = 50 – 16t and y =100 – 4t’, where v, is in meters per second, y is in meters, and t is in seconds.It is also known that x = 0 when t – 0. Plot the path of the particle and determine its velocity and acceleration when the position y = 0 is reached.

A motor drives two loads. One has rotational motion. It is coupled to the motor through a reduction gear with a = 0.1 and efficiency of 90%. The load has a moment of inertia of 10.kg- m ^ 2 and a torque of 10 N-m. Other load has translational motion and consists of 1000 kg weight to be lifted up at an uniform speed of 1.5 m/s. Coupling between this load and the motor has an efficiency of 85%. Motor has an inertia of 0.2kg – m ^ 2 and runs at a constant speed of 1420 rpm. Determine equivalent inertia referred to the shaft and power developed by the motor.
