work, Mr. Nakset goes home and watches Netflix. One evening, while he was watching, he sees a cockroach on the wall, 1 ft away and 7.5 ft above where he was sitting. In an attempt to kill the cockroach, he throws a thick University Physics book at it. If he throws the book at an angle of 80 degrees with the horizontal with a velocity of 18 ft/s, will he be able to hit the cockroach? Why or why not?

A surveyor measures the distance across a straight river by the following method: starting directly across from a tree on the opposite bank, he walks x = 1.00 102 m along the riverbank to establish a baseline. Then he sights across to the tree. The angle from his baseline lo the tree is = 35.0 (Fig. P1.53). How wide is the river? Figure P1.53
A landscape architect is planning an artificial waterfall in a city park. Water flowing at 1.70 m/s will leave the end of a horizontal channel at the top of a vertical wall h = 2.35 m high, and from there it will fall into a pool (Fig. P3.42). (a) Will the space behind the waterfall be wide enough for a pedestrian walkway? (b) To sell her plan to the city council, the architect wants to build a model to standard scale, which is one-twelfth actual size. How fast should the water flow in the channel in the model?

Alishba wakes up late and runs to school, covering a distance of 2.55 km in a direction of [N200 E] as measured from her home. She then realizes that her friend Lydia has her homework and races over to his house 0.5 km away [W] from the school. The two friends then decide it’s not worth going to class late so they go off to the mall that is 2.8 km [W500 S]. a) What is Alishba’s total displacement? b) If the total time taken by Alishba to run to school then over to the friend’s house was 25 minutes, what was her average velocity?

These two questions are very similar. However, when I was working through them and also looking at the textbook answers, question 32 includes V0 in the formula (x-x0)=V0t+1/2at^2. However, in questions 36 V0 is 0. If this is the case why isn't V0=0 in question 32. I'm referring to part A in both questions. I am confused! please help!
I got part A and C correct. I got the same answer as you for part B but it is saying it is incorrect.
Can you please explain to me how the t was solved based on the solution. The answer is correct.
