Unformatted text preview: independent of their mass (excluding the effect of air resistance). Kitchen Faucets : h = height of faucet outlet above sink Assume v water at faucet outlet is ~0, and ~same for all faucets ( same flow rate). Then v water = when it reaches the sink, so that v water at sink. gh 2 h v water Standard faucet: Gooseneck faucet: h=15 cm (~6 inches) h=30 cm (~12 inches)  At level of sink, more splashing! h 2 , , std goose std water goose water h h v v Suppose that the height of the Suspension Bridge were doubled. By what multiplicative factor would the time for the rock to fall change? t (2h) / t (h) = ?
