1)Two boats start together and race across a 48-km-wide lake and back. Boat A goes across at 48 km/h and returns at 48 km/h. Boat B goes across at 24 km/h, and its crew, realizing how far behind it is getting, returns at 72 km/h. Turnaround times are negligible, and the boat that completes the round trip first wins. A) By how much? B)What is the average velocity of the winning boat? 2)A race car moves such that its position...

Problem 3 (a) You and a friend are bicycling from Springdale to Bentonville. You maintain a constant speed for the entire distance of the trip. Your friend, however, goes 1mph faster than you for the first half of the time to Bentonville and 1mph slower than you for the second half of the time. Who gets to Bentonville first? Explain your reasoning. Wou ld your answer have been different if I had specified the different velocities for 1/2 of the...

My Notes Ask Your Teacher participate in a race over a 1.10 km long course. The horse travels at a speed of 15.0 m/'s and the squirrel can do 2.50 m/s. The horse runs for n stops to tease the slow-moving squirrel, which eventually passes by. The horse waits for a while after the squirrel passes and then runs toward the finish line. Both animals cross the finish line at the exact same instant. Assume both...

Please show all your work.
5) Acceleration is to velocity as velocity is to position . aaux"# r where vr įs the instantaneous velocity. So the average acceleration is about how rapidly the instantaneous velocity is changing, and the sign tells about the direction of the change. At For the pendulum, you made estimates of the instantaneous velocity for ←2.05[s] and t= 2.5%]. Also, the average speed and average velocity estimates that you made at other times may be reasonable...

2) You and your friend Barbara are in two different reference frames (rf) and are discussing/arguing about where and when a firecracker exploded. You are in a spaceship speeding past Barbara's "Earth" rf at 99.9% the speed of light (moving to her right) At zero time in both rfs, both your origins coincide, i.e. your spaceship is at her location at t 0. Barbara states unequivocally that the firework exploded at t 1 nanosecond (ns) exactly 2 meters to her...
