PLEASE ANSWER I NEED I HELP. A bike path starts on one side of the parking lot, goes around a small pond, and comes out on the other end of the parking lot. Following the path, a biker rides 100.0 meters directly east, then turns south and rides 200.0 meters. From there, she turns and rides 150.0 meters at an angle of 30.0° south of west. Turning one last time, she rides 250.0 meters at an angle of 60.0° north of west. What is her final displacement (distance and direction) from her starting point?

Asuppose a suitcase has a mass of (m) 30 kg and a net force (n) of 10 kg*m/s. what is the acceleration rate of the suitcasein m/s? show your work to support your answer.

Which of the following compounds would be primarily ionic? methane, ch4, ammonia nh3, calcium chloride, cacl2, or carbon dioxide, co2

Suppose that a mass of 2 kg is attached a spring whose spring constant is 50. the system is damped such that b = 12 . the mass is set in motion with an initial velocity of -8 m/s at a position 0 meters from equilibrium. set up and solve a differential equation that models this motion. write your solution in the form a cos ( ω t − α ) where α is a positive number. use your solution to fill in the information below: what is the amplitude of the motion? what is the value of ω ? what is the phase shift?
