3. Edward was tasked to find the displacement of a submarine in the ocean. He was informed that the submarine moved at a distance of 12.5 km West, 6.7 km North, and 15.7 km East. The displacement of the submarine from the ship is

A speed boat can make a trip of 100 km in one hour and 30 minutes if it travels upstream If it travels downstream, it will take one hour and 15 minutes to travel the same distance. What is the speed of the boat in clam water?   A. 80 kph B. 123.33 kph C. 66.67 kph D. 73.33 kph

A car is going 20m/s in 10sec. How far the car goes?   1. 2m   2. 0.5 m   3. 200m   4. 50.2 m

Car A is traveling at the constant speed of 67 km/h as it rounds the circular curve of 320-m radius and at the instant represented is at the position e = 46°. Car B is traveling at the constant speed of 98 km/h and passes the center of the circle at this same instant. Car A is located with respect to car B by polar coordinates r and 0 with the pole moving with B. For this instant determine va/B and the values of i and O as measured by an observer in car B. 320 m B
