In reaching her destination, a backpacker walks with an average velocity of 1.14 m/s, due west. This average velocity results, because she hikes for 5.56 km with an average velocity of 3.44 m/s due west, turns around, and hikes with an average velocity of 0.376 m/s due east. How far east did she walk (in kilometers)? West East 3p Number Units km

At an air show, a jet plane has velocity components vx =695km/h and vy  =415km/h  at time 4.35 s and vx =938km/h and vy =365km/h at time 7.52 s.   Please answer A,B,C,D Thank you.

The speed of propagation of the action potential (an electric signal) in a nerve cell depends (inversely) on the diameter of the axon(nerve fiber). If the nerve cell connecting the spinal cord to your feet is 0.9 m long and the nerve impulse is 16 m/s. How long (in s) does it take for the nerve signal to travel this distance ?

A student drove to the university from her home and noted that the odometer reading of her car increased by 12.0 km. The trip took 17.9 min. a.If the straight-line distance from her home to the university is 10.310.3 km in a direction 28.028.0º south of east, what was her average velocity? (magnitude and direction south of east) b.If she returned home by the same path 6.50h after she left, what was her average speed for the entire trip?

Chapter 02, Problem 10 In reaching her destination, a backpacker walks with an average velocity of 1.26 m/s, due west. This average velocity results, because she hikes for 6.62 km with an average velocity of 2.54 m/s due west, turns around, and hikes with an average velocity of 0.381 m/s due east.

Current Attempt in Progress In reaching her destination, a backpacker walks with an average velocity of 1.41 m/s, due west. This average velocity results, because she hikes for 6.94 km with an average velocity of 2.42 m/s due west, turns around, and hikes with an average velocity of 0.638 m/s due east. How far east did she walk (in kilometers)? VW 71 Number i West Units dw VE East dE

The functional relation between the displacement x in meters and the time t in seconds is given by x = At 2 + Bt + C where A, B, and C are constants. Find the functional relationship between the (a) velocity and the time, and (b) acceleration and the time. What are the values of the velocity and the acceleration at the instant t= 4seconds?

A runner, jogging along a straight-line path, starts at a position 60.0 m east of a milestone marker and heads west. After a short time interval he is 15.7 m west of the mile marker. Choose east to be the positive x-direction. What is the runner’s displacement from his starting point? Enter a positive value if the displacement is toward east of the milestone and a negative value if the displacement is toward west of the milestone.
