SOLUTION TO HOMEWORK PROBLEMS Chapter-4: MOTION IN TWO DIMENSIONS 1 A particle starts from the origin at t = 0 with a velocity of 6.0[pic] m/s and moves in the xy plane with a constant acceleration of (-2.0[pic] + 4.0[pic]) m/s2. At the instant the particle achieves its maximum positive x coordinate‚ how far is it from the origin? [pic] 2 At t = 0‚ a particle leaves the origin with a velocity of 5.0 m/s in the positive y direction. Its acceleration is given by [pic] = (3.0[pic] - 2.0[pic])
