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...

A car is initially moving at 9.9 m/s in the positive x direction and accelerates at a constant acceleration of 3.4 m/s2 in the positive x direction for 6 seconds. It then immediately has an acceleration of 6.6 m/s2 in the negative x direction. After some time, its velocity is 27.6 m/s in the negative x direction. What is the average velocity for the entire trip in m/s? Indicate the negative x direction by including a negative sign but do...
