1.A 2-mm particle has a specific gravity of 2.7. What is it'sspecific surface in m2/g if the particle is a perfectsphere? calculate specific surface.
2.Immediately after the bouncing golf ball leaves the floor itscomponent of velocity are Vx= 0.662 m/s and Vy= 3.66 m/s. determinethe horizontal distance from the point where the ball left the floor to the point where it hits the floor again. the ball leaves the floor at x=0, y=0. determine the ball's y coordinate as afunction of x.
