Q1. A parachutist descending at a speed of 14.1 m/s loses a shoe at an altitude of 48.50 m. (suppose the positive direction is upward.)

(a) When does the shoe reach ground?

(b) What is the velocity of the shoe just before it hits ground?

Q2. A constant horizontal force Fa pushes a 3.70 kg FedEx package across a frictionless floor on which a xy coordinate system has been drawn. it gives the package's x and y velocity components versus time t. (The vx axis is marked in increments of 1.28 m/s and the vy axis is marked in increments of 2 m/s.)

(a) What is the magnitude of Fa?

What is its direction? (counter clockwise from the positive x axis)
