A box of mass sits on the floor of an elevator. The area of thebottom surface of the box is 0.250 m2. When the elevator is movingupward at a constant speed of 2.00 m/s the pressure the box exertson the floor is 981 pascal. (Note: One Pascal equals one Newton persquare meter; 1 Pa = 1 N/m2). Calculate the pressure the box exertson the floor while the elevator a. slows uniformly from an upwardspeed of 2.00 m/s to zero in 3.00 seconds. b. accelerates uniformlyfrom rest to a downward speed of 2.00 m/s in 3.00 seconds. c. slowsuniformly from a downward speed of 2.00 m/s to zero in 3.00seconds. d. is moving downward at a constant speed of 2.00 m/s e.accelerates uniformly from rest to an upward speed of 2.00 m/s in3.00 seconds f. is at rest.
