Drag Force: A spherical particle of radius 5.9 cm and a mass of 229 g is moving through a fluid of the same density. (This means you can ignore the effects of gravity.) 1 The position of the particle is given by x (t) = In (1+ bvot), where x is its position and t is the elapsed time. The initial speed vo is 17.4 m/s, and the constant b is 0.4 m-1. (b) What is the velocity of the particle after 2.9 seconds? (c) What is the acceleration of the particle after 2.9 seconds?
ICE ANOTHER Alloys of gold are rated in karats, a dimensionless unit that is used to indicate the proportion of gold by weight in a gold-containing alloy. If an alloy is one part in twenty-four pure gold, then it is classified as one karat gold. The density of gold is 19.3 × 103 kg/m3. Determine the volume of gold in a 23.0 karat gold necklace that has a weight of 1.63 N. m3 Additional Materials O Reading
