• The questions on this assignment that have to be submitted can be done without a you challenge yourself by putting the calculator aside for those. Consult the appendix at the end to calculate the relevant sines, cosines and tangents. 1. Submit for grading. I'm standing on top of building such that my hand is 70 m from the ground. At t=0 sI throw a ball up with a speed of 25 m/s. Find the time it takes for the ball to hit the ground. 2. (a) Submit for grading. For each of the scenarios given below explain qualitatively using no more than four sentences if the object will change its speed and/or direction. For the latter, indicate which direction the object turns in. Scenario 1 Scen ar io 2 1 80 Scenario 3 90 Scenario 4. Figure 1: Figures for question 2a. 18 18
