Problem 115
Object 1 starts at \(25 \mathrm{~m}\) and moves with a velocity of \(-5.6 \mathrm{~m} / \mathrm{s}\). Object 2 starts at \(13 \mathrm{~m}\) and moves directly toward object 1 . The two objects collide \(0.61 \mathrm{~s}\) after starting. (a) What is the velocity of object 2? (b) What is the position of the objects when they collide?

Problem 116
On your cousin's wedding day you leave for the church \(30.0 \mathrm{~min}\) before the ceremony is to begin, which should leave plenty of time since the church is only \(17.0 \mathrm{~km}\) away. On the way, however, you have to make an unanticipated stop because of road construction work. As a result, your average speed for the first \(15 \mathrm{~min}\) is only \(12.0 \mathrm{~km} / \mathrm{h}\). What average speed do you need to have on the remainder of the trip to get you to the church on time?
