7) Sailboat travels at a speed 20.0 km/h on Georgian Bay in a direction 30.0° west of north with no land in sight while a motorboat travels 20.0° east of north at 25.0 km/h. What is velocity (magnitude and direction) of the sailboat relative to the motorboat?
9) A particle moves in a straight line in such a way that s=2t feet where t is in seconds. Is the acceleration zero, or has it constant or varying acceleration.
A motorcycle starts from rest at t = 0 and travels along a straight road with a constant acceleration of 7 ft/s2 until it reaches a speed of 60 ft/s. Afterwards it maintains this speed. Also, when t = 0, a car located 8,000 ft down the road is traveling toward the motorcycle at a constant speed of 40 ft/s. A) Determine the time when they pass each other. B) Determine the distance traveled by the motorcycle when they pass each other.
