Express your answer to two significant figures and include appropriate units.A spelunker is surveying a cave. She follows a passage 160 m straight west, then 230 m in a direction 45degree east of south, and then 280 m at 30 degree east of north. After a fourth unmeasured displacement, she finds herself back where she started.
- A hiking girl needs to go 39.2 km straight North to get to base camp, instead the compass confuses her and she travels 17.248 km at a 3.9° deflection East from straight North. Then she realizes what she has done and so guesses an angle of 17.8° deflection West of straight North and then hikes 30.576 km. What is the magnitude of her displacement from where she is now located to base camp. (put your answer is standard units)The average distance of the earth from the sun is about 1.5 x 108 km (Figure 1). Assume that the earth's orbit around the sun is circular and that the sun is at the origin of your coordinate system. (a) Estimate the speed of the earth as it moves in its orbit around the sun. Express your answer in miles per hour with the appropriate number of significant figures. (b) Estimate the angle between the position vector of the earth now and what it will be in 4 months. (c) Calculate the distance between these two positions.Jack goes for a ride on a ferris wheel that has a radius of 37 meters. The center of the ferris wheel is 49 meters above the ground. He starts his ride at the 12 o'clock position and travels counter clockwise. Define a function g that represents Jack's horizontal distance in meters relative to vertical midline of the wheel in terms of the angle (measured in radians) Jack makes with the center.
