A mass weighing 4 pounds is attached to a spring whose constant is 2lb/ft. The medium offers a damping force that is numerically equal to the instantaneous velocity. The mass is initially released from a point 1foot above the equilibrium position with a downward velocity of 14ft/s. a) Determine the time at which the mass passes through the equilibrium position. (Use g=32ft/s2 for the acceleration due to gravity.)
b) Find the time after the mass passes through the equilibrium position at which the mass attains its extreme displacement from the equilibrium position.
c) What is the position of the mass at this instant?

Juliana says that she can use the patterns of equivalent ratios in the multiplication table below to write an infinite number of ratios that are equivalent to 6: 10. which statement explains whether juliana is correct? she is correct because she can multiply 6 and 10 by any number to form an equivalent ratio. she is correct because 6: 10 can be written as 1: 2 and there are an infinite number of ratios for 1: 2. she is not correct because the multiplication table does not include multiples of 10. she is not correct because 6: 10 is equivalent to 3: 5 and there are only 9 ratios in the multiplication table that are equivalent to 3: 5.
