Two boats start together and race across a 60-km-wide lakeand back. Boat A goes across at 60 km/h and returns at60 km/h. Boat B goes across at 30 km/h, and its crew,realizing how far behind it is getting, returns at 90 km/h.Turnaround times are negligible, and the boat that com-pletes the round trip first wins. (a) Which boat wins andby how much? (Or is it a tie?) (b) What is the average ve-locity of the winning boat?

Step 1: Given that : Width of river (L) = 60 kmCrossing Velocity of boat A is :VA1=60…

On a 200 km bike cycle ride, you ride the first 90 km at an average speed of 20 m/s. What mustyour average speed over the next 40 km be to have your average speed for the total 200 km be?(a) 60 m/s?
Ih took Joseph 30 minutes longer to drive 375 km from along the north shore of a river from Apex to Rounder than it took to return along the south shore, a distance of 420 km. On the retum trip the highway was wider and in better condiftion, so he was able to average 10 km/h faster. What was his average speed on cach part of the trip?
A ball rolls 10.0m [S] in a time of 6.00 seconds, hits a wall, and rolls back 21a distance of 15.0m [N] in a time of 10 seconds. Determine the average speed of the ball. Question: When solving for speed, would the time be 16 seconds or 10-6= 4 seconds? And why?
In the blizzard of ’88, a rancher was forced to drop hay bales from an airplane to feed her cattle. The plane flew horizontally at 160 km/hr and dropped the bales from a height of 80 m above the flat range, (a) She wanted the bales of hay to land 30 m behind the cattle so as to not hit them. Where should she push the bales out of the airplane? (b) To not hit the cattle, what is the largest time error she could make while pushing the bales out of the airplane? Ignore air resistance.

A truck is traveling east at 82 km/h. At an intersection 34 km ahead, a car is traveling north at 60 km/h. (a) How long (in minutes) after this moment will the vehicles be closest to each other? b) How far apart will they be at that point (in km)?
Two students are canoeing on a river. While heading upstream,they accidentally drop an empty bottle overboard. They then continuepaddling for 60 minutes, reaching a point 2.0 km farther upstream. Atthis point they realize that the bottle is missing and, driven by ecologicalawareness, they turn around and head downstream. They catch up with andretrieve the bottle (which has been moving along with the current) 5.0 kmdownstream from the turnaround point. What would the canoe speed in a still lake be for the same paddling effort?
A seagull flies at a velocity of 9.00 m/s straight into the wind. (a) If it takes the bird 18.0 min to travel 6.00 km relative to the earth, what is the velocity (in m/s) of the wind? m/s (b) If the bird turns around and flies with the wind, how long (in s) will he take to return 6.00 km? S (c) Discuss how the wind affects the total round-trip time compared to what it would be with no wind.
(c) Tests reveal that a normal driver takes 0.75 s before he or she can react to a situation to avoid accident or collision. It takes about 3.00 s for a driver with having 0:10% of alcohol in his syst em to do the same. If such drivers are travelling on a straight road at 44:00 ft=s and their cars decelerates at 0:68 m-s, ded ermine the shortest st opping distance, d, for each from the moment they see the pedestrians. Refer to Figure 1. [1 m = 3.2808399 ft] 2

The brakes are applied to a moving car, causing it to uniformly slow down. While slowing, it moves a distance of 40.0 m in 7.00 s to a final velocity of 2.05 m/s, at which point the brakes are released. (a) What was its initial speed (in m/s), just before the brakes were applied? i have tried so many ways to solve this and i cant please explain
A bus has an initial speed of 10 m/sec. It is picking up speed with an acceleration of 6 m/sec/sec over the next 5 seconds. O Give the speed of the car in m/sec at each second.
