Full annealing is accomplished by heating at a temperature approximately how many degrees Celsius above either A3 line (for compositions less than the eutectoid) or A1 line (for compositions greater than the eutectoid)? 25°C 40°C 50°C 55°C 70°C g

Aparticle moves in the xy plane with constant acceleration. at time zero, the particle is at x = 6 m, y = 8.5 m, and has velocity ~vo = (9 m/s) ˆı + (−2.5 m/s) ˆ . the acceleration is given by ~a = (4.5 m/s 2 ) ˆı + (3 m/s 2 ) ˆ . what is the x component of velocity after 3.5 s? answer in units of m/s.
