Unformatted text preview: h =1.7 x10-1 kg/m 3 ). The sphere is then tied to the bottom of a pool of fresh water (ρ w =1000 kg/m 3 ) by a string. Determine the tension in the string if the radius of sphere is 0.10 meters. 5) A solid foam ball (ρ= 100 kg/m 3 ) of radius 0.15 meters is dropped from a height of 3 meters above the surface of a pool (ρ= 1000 kg/m 3 ). Neglecting air resistance and any fringe effects(as the ball enters the pool) determine: (a) the acceleration of the ball while its in the air (density of air = 1.29 kg/m 3 ) (b) the velocity of the ball just before it hits the water (c) the acceleration of the ball while it is in the water (d) the depth to which the ball goes before stopping 6) A block of wood of mass 30 kg is floating in a pond of density 1000 kg/m 3 such that half of the block is submerged. Determine the density of the object....
