Answer:
9.68 m/s2
Explanation:
If it completes 1 revolution, or 2π for every 36 seconds, then its angular speed ω is 2π/36 = 0.1745 rad/s
So the centripetal acceleration would be
The tangential acceleration is:
When the passenger is on top of the wheel, the tangential acceleration is horizontal, while centripetal acceleration is vertical, acting upward, gravitational acceleration g is 9.8 m/s2 acting downward. The total vertical acceleration is 0.3 - 9.8 = -9.5 m/s2
So the magnitude of the total acceleration consisting of horizontal and vertical components is:

I know what thats like. Either that or they don't trust you. It could be something personal or they just dont wanna talk. But i wouldn't push. Just let them talk if they want to
The correct answer is A car travels South for 5 miles, turns around, and travels North for 8 miles.
Explanation:
Displacement is determined by the change in position. This means there is displacement if the initial position of a body such as a car is different from the final position. Also, the displacement is considered in terms of direction (North, South, East, West). In this context, if a car travels South or North and then returns to its initial position there is no displacement.
According to this, the only option that shows a displacement North is "A car travels South for 5 miles, turns around and travels North for 8 miles" because in this case, the car had a change in position as it first moved 5 miles south (a displacement of 5 miles South) and then 8 miles north, which changes the displacement to 3 miles North (5 miles South - 8 miles North = 3 miles North).
