1. Center of Mass (5 points). Shape of mount Fuji may be modeled approximately as a cone. The half angle at the apex is estimated to be 65 degrees. Height of the apex is approximately 3800m. At what height is the center of mass? Assume that the material of mount Fuji has uniform density. 2 Impulse and Momentum 2.1 (5 points) A stream of water impinges on a stationary \"dished" turbine blade. The mass flow rate of the . . k . stream IS m (f). The velocuty of the stream coming towards the blade is u (m/s) and it gets deflected by 180 degrees and returns with velocity u (m/s) as shown below. Calculate the force exerted on the blade
