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 3.30 m/s2 As it passes x= -7.40 m its speed is 4.90 m/s.
a) Calculate the speed of the mass as it crosses the origin, x=0 (in m/sec).
b) Calculate the total travel time (in sec) from xi to x=0 (in sec).
c) Find the initial postion of the mass on the -x axis, xi.
