can you show how to solve step by step

IS 3.9 (Part 2) Assignment 1. A 13ft ladder is leaning against a wall. If the top of the ladder slips down the wall at a rate of 2ft/s, how fast will the foot be moving away from the wall when the top is 5ft above the ground? y = oft all ty.dy = 0 By= 13 2. A softball diamond is a square whose sides are 60ft long. Suppose that a player running from first to second base has a speed of 25ft/s at the instant when she is 10ft from second base. At what rate is the player's distance from home plate changing at that instant? 3. A rocket, rising vertically, is tracked by a radar station that is on the ground 5km from the launch pad. How fast is the rocket rising when it is 4km high and its distance from the radar station is increasing at a rate of 2000km/h
