Question

2. (5 points) A particle having resistance with the magnitude of F=cv. In the coordinate system differential equation of motion when it goes up is a mass of m is thrown vertically upwards, and is subjected to the air shown in Fig. 4, the particle's where t is time leration km/2. m. 3. ( 10 points) The velocity of a particl e is given by v=6f+8t3j+(3t+ 5)kms, the particle is at the origin when t=0, when t=2s, the particle's acce vector is a = the particle's position vector is 4. (20 points) As shown in Fig. 5, the right curved-rod OAB rotates around axis O at a steady angular velocity a, OA=r. Ring M moves along rod AB and the fixed horizontal rod OC. M is chosen to be the moving point, the moving coordinate is fixed to OAB. When e-60°, the magnitude of convected velocity is v' ; the magnitude of absolute velocity is o B. M. C. ; the magnitude of convected ; the magnitude A. acceleration is a.- of Coriolis acceleration is ac- 5

Explanation / Answer

Equation of motion for a body thrown upward having wind resistance of CV is mdv÷dt=CV + mg.
