A particle moves along the x axis. It is initially at the position 0.270 m, moving with velocity 0.210 m/s and acceleration -0.280 m/s2, Suppose it moves with constant acceleration for 4.,50 s. (a) Find its position at the end of this time interval. -1.620 (b) Find its velocity at the end of this time interval. -1.05 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 at the end of this time interval. -0.122 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. m/s
