True or False: The more mass an object has, the faster it will fall.

A pressure of 2.5 atm is equivalent to a. 41 kPa. b. 1900 mm Hg. c. 3.0 * 102 mm Hg. d. 2.5 kPa.

A particle 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.
