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…

Let's assume that East Lake Road runs due East from the Boston Store in Erie, and there are mile markers along it ("Ten Miles from the Boston Store", etc.) A car starts at the 12 mile marker going East at 2 PM, turns around at the 20 mile marker at 3 PM, and stops at the 8 mile marker at 4 PM. What is the total displacement of the car from 2 PM to 4 PM, in miles? (Use "+" for East, and "-" for West) O +4 O-20 O +20 O -4 O none of the answers is correct

Hi, I need help with this physcis problem. I've gone over it multiple times and can't firgure it out. Anyway you can help? A car, initially at rest, accelerates at a constant rate of 2 m/s2 due east (choose east as the positive direction; round your answer to the nearest meter per second; include units)What is its velocity after 1 second? What is its velocity after 2 seconds? What is its velocity after 3 seconds? What is its velocity after 4 seconds? What is its velocity after 5 seconds? What is its velocity after 9 seconds? If instead a car accelerates at a constant rate of 5 m/s2 due eastWhat is its velocity after 1 second? What is its velocity after 2 seconds? What is its velocity after 3 seconds? If instead a car accelerates at a constant rate of 5 m/s2 due westWhat is its velocity after 1 second?
two car with a distance of 100m between them are moving in the same direction with the same speed. At t=0 s , the cars start to apply constant acceleration with the same magnitude but in opposite directions, simultaneously. at the 5th second, the cars are the same position, and one of the cars is stopping. calculate the velocity of the moving car at the 5th second. (ıf you use g ; take g = 10m/s2)
