Physics forces problem!!?

Researchers often use force plates to measure the forces that people exert against the
floor during movement. A force plate works like a bathroom scale, but it keeps a record
of how the readings change with time. The figure shows the data from a force plate as
a woman jumps straight up and the lands.
(a.) What was the vertical component of her acceleration during push-off?
(b.) What was the woman’s speed as her feet left the floor?
(c.) What was the vertical component of her acceleration while in the air?
(d.) What was the vertical component of her acceleration during the landing?
