Beryl (m=45kg) is standing in an elevator that is movingvertically upward at a speed of 3 m/s. 1.5 s later, the elevatorand Beryl are moving vertically downward at a speed of 5 m/s.Beryl's feet remain in contact with the elevator's floor at alltimes, and that is Beryl's only point of contact with the elevator.(The y axis is vertical and positive upward)
What is the y-component of Bery;'s acceleration during that timeinterval?
What is the magnitude of Beryl's weight?
What is the magnitude of the normal force that the elevatorexerts on Beryl during that time interval?
