(b) What is her initial acceleration if she is initially stationary and wearing steel-bladed skates that point in the direction of Ftot? (Assume friction is negligible. Enter the magnitude only.) m/s2 (c) What is her acceleration assuming she is already moving in the direction of Ftot? (Assume friction is negligible. Enter the magnitude only.)
Calculate the mass in mg of sodium borohydride (molecular weight=37.85 g/mol) which are dispensed when 1.50 mL of a 4.00 M solution are transferred to a reaction vessel
1. Name an everyday object that has the same diameter-to-thickness ratio as the Milky Way, and demonstrate that it does using estimates of the size/thickness; this should be an object with a generally similar shape to the milky way. Draw this object, and the Milky Way, edge-on and face-on. 2. The sun and other nearby stars […]

A disk-shaped merry-go-round of radius 2.83 and mass 185 rotates freely with an angular speed of 0.611 . A 56.4 person running tangential to the rim of the merry-go-round at 3.01 jumps onto its rim and holds on. Before jumping on the merry-go-round, the person was moving in the same direction as the merry-go-round’s rim.
