Aparticle moves along the x axis. its position is given by the equation x. 1.6 + 2.6-3.5宀with x in meters and t in seconds. (a) determine its position when it changes direction. (b) determine its velocity when it returns to the position it had at t- 0? (indicate the direction of the velocity with the sign of your answer.) is the initial velocity positive or negative? what sign do expect the velocity to have when the particle returns to its starting point? m/s need ? 12.-/10 points serpse10 2.7 op020 my notes ask your a crate slides across a frictionless horizontal surface with constant acceleration 3.90 m/s and over a time interval reaches a final velocity of 10.0 m/s. a) if its initial velocity is 5.00 m/s, what is its displacement (in m) during the time interval? (indicate the direction with the sign of your answer.) b) what is the distance it travels (in m) during this interva e) if its initial velocity is-5.00 m/s, what is its displacement (in m) during the time interval? (indicate the direction with the sign of your answer.) a what is the total distance it travels (in m) during the interval in part (c)? need ? rea 13. -30 points serpse 10 2.7p017mi mty notas ask your an object moving with uniform acceleration has a velocity of 11.0 cm/s in the positive x direction when its x coordinate is 2.97 cm. if its x coordinate 2.75 s later is -5.00 cm, what is its acceleration?
