A particle leaves the origin with an initial velocity v⃗ =(2.40m/s)x^, and moves with constant acceleration a⃗ =(−1.90m/s2)x^+(3.20m/s2)y^. How far does the particle move in the x direction before turning around? What is the particle's velocity at this time? Calculate the particle's position at t = 0.500 s, 1.00 s, 1.50 s, and 2.00 s. Use these results to sketch x and y positions versus time for the particle.

A 4 kg particle moves along an x axis, being propelled by a variable force directed along that axis. Its position is given by x = 1 m + (6 m/s)t + ct2 - (4 m/s3)t3 with x in meters and t in seconds.The factor c is a constant. At t = 4 s the force on the particle has a magnitude of 32 N and is in the negative direction of the axis. What is c?
