It is measured that 80% of a body's volume is immersed in seawater of density 1030 kg/m^3. a) What is the specific gravity of the sea water? b) Determine the volume of the seawater displaced. c) Calculate the density of the body. d) Calculate the relative density of the body.

Show the complete solution. Use the correct number of significant figures In the figure, block 1 of mass m1 slides from rest along a friction less ramp from height h = 3.2 m and then collides with stationary block 2, which has mass m2 = 5 m1. After the collision, block 2 slides into a region where the coefficient of kinetic friction μk is 0.3 and comes to a stop in distance d within that region. What is the value of distance d if the collision is (a) elastic and (b) completely inelastic?

Show complete solution. Use the correct number of significant figures. 1. In the figure, two blocks are connected over a pulley. The mass of block A is 12.0 kg and the coefficient of kinetic friction between A and the incline is 0.140. Angle θ of the incline is 32.0°. Block A slides down the incline at constant speed. What is the mass of block B? Answer: _______ (the tolerance is +/-2%) 2. In the figure, a 4.1 kg block slides along a track from one level to a higher level after passing through an intermediate valley. The track is friction less until the block reaches the higher level. There a frictional force stops the block in a distance d. The block's initial speed is v0 = 5.7 m/s, the height difference is h = 1.1 m, and μk = 0.583. Find d. Answer:________ (the tolerance is +/-2%)
