Predict/Calculate A turntable with a moment of inertia of 5.4 × 10 −3 kg · m 2 rotates freely with an angular speed of 33 1 3 rpm. Riding on the rim of the turntable 15 cm from the center, is a cute. 32-g mouse (a) If the mouse walks to the center of the turntable, will the turntable rotate faster slower, or at the same rate? Explain (b) Calculate the angular speed of the turntable when the mouse reaches the center.

The force of the quadriceps (Fq) and force of the patellar tendon (Fp) is identical (i.e., 1000 N each). In the figure below angle in blue is Θ and the in green is half Θ (i.e., Θ/2). A) Calculate the patellar reaction force (i.e., R resultant vector is the sum of the horizontal component of the quadriceps and patellar tendon force) at the following joint angles: you need to provide a diagram showing the vector and its components for each part. a1) Θ = 160 degrees, a2) Θ = 90 degrees. NOTE: USE DO NOT USE LAW OF COSINES, NO COMPLICATED ALGEBRAIC EQUATIONS OR ANYTHING ELSE, ETC. Question A has 2 parts!
