A particle moves along the x axis. It is initially at the position 0.180 m, moving with velocity 0.210 m/s and acceleration -0.210 m/s2. Suppose it moves with constant acceleration for 4.50 s. (a) Find the position of the particle after this time. Your response differs from the correct answer by more than 100%. m (b) Find its velocity at the end of this time interval. Your response differs from the correct answer by more than 100%. m/s Next, assume it moves with simple harmonic motion for 4.50 s and x = 0 is its equilibrium position. (Assume that the velocity and acceleration is the same as in parts (a) and (b).) (c) Find its position. Your response differs from the correct answer by more than 10%. Double check your calculations. m (d) Find its velocity at the end of this time interval.
