A mass of 0.11 kg is initially at rest at an unknown position on the -x axis, xi. It begins accelerating towards x=0, with a constant acceleration of 2.50 m/s2 As it passes x= -7.30 m its speed is 5.18 m/s. Calculate the speed of the mass as it crosses the origin, x=0 (in m/sec).

use the equation relating initial velocity, final velocity, and displacement and constant acceleration

. Calculate the total travel time (in sec) from xi to x=0 (in sec).

Find the initial postion of the mass on the -x axis, xi.
