Use the worked example above to you solve this problem. a hiker begins a trip by first walking 25.5 km southeast from her base camp. on the second day she walks 42.0 km in a direction 60.0° north of east, at which point she discovers a forest ranger's tower. (a) determine the components of the hiker's displacements in the first and second days. ax = km ay = km bx = km by = km (b) determine the components of the hiker's total displacement for the trip. rx = km ry = km (c) find the magnitude and direction of the displacement from base camp. magnitude km direction ° north of east

The slope of a good speed time indicates ? a. velocity b. acceleration c. direction d. speed

Iwill give 30 points to whoever answers ! what is the formula for actual mechanical advantage and ideal mechanical advantage?

Thomas his older brothers, who own a junk yard, on the weekends to earn extra money. he likes to them push broken-down cars to the back of the junk yard because it makes him feel strong. last saturday, they pushed three cars with different weights, and he noticed he used different amounts of force for each one. the cars were the following weights: white car: 2,700 kg red car: 1,500 kg blue car: 2,100 kg think about how much force is needed to move each car. which correctly lists the cars in order from the most to least amount of force needed to move them? a) white, blue, red b) blue, red, white c) red, white, blue d) white, red, blue
