A woman walks 2.05 km south and then 2.75 km east, all in 2.60 hours. (a)What is the magnitude (in km) and direction (in degrees south of east) of her displacement during the given time? (b) What is the magnitude (in km/h) and direction (in degrees south of east) of her average velocity during the given time? (c)What was her average speed (in km/h) during the same time interval?

Suppose that a particle begins its motion from the origin and meets the velocity (in m / s) given by: vx (t) = 2.50t vy (t) = 3.50√t.    for t> 0 in seconds. Find the speed of the particle at t = 5.00 s  What is the acceleration vector (in rectangular components) at t = 2.00 s ? Find the magnitude of the displacement between t = 0.00 s and t = 6.00 s

A car is traveling east at 17.5 m/s when it turns due north and accelerates to 32.5 m/s, all during a time of 5.00 s. Calculate the magnitude of the car's average acceleration (in m/s2).

You walk for 1000 m northwards at a constant velocity of 3 m/s. Then you turn around, and walk with an average velocity of 0.5 m/s due south. From your starting point to your destination, your overall average velocity for the entire trip is 1.2 m/s due north. What is the northward total displacement during the entire trip?

A car is traveling west at 17.5 m/s when it turns due north and accelerates to 32.5 m/s, all during a time of 4.00 s. Calculate the magnitude of the car's average acceleration (in m/s2).

The vertical displacement (in m) of a plane is  1.5 t2 up; t is the time (in s) after takeoff. The plane releases a package 2.0 s after takeoff. What is the magnitude of the velocity (in m/s) when the packaged is released? Report your answer in the appropriate number of significant digits. Answer value

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. How far east did she walk (in kilometers)? dw VE West East dɛ Number Units the tolerance is +/-2% Click if you would like to Show Work for this question: Open Show Work

An Australian emu is running due north in a straight line at a speed of 13.0 m/s and slows down to a speed of 9.70 m/s in 2.30 s. (a) What is the magnitude and direction of the bird’s acceleration? (b) Assuming that the acceleration remains the same, what is the bird’s velocity after an additional 1.30 s has elapsed?

A vehicle travels at a speed of 4 m/ sec along a horizontal Circular road that has a radius of 50m its speed is then increased by ú= (0.05.s) m/sec² for a short distance from S = 0, where s is in meters. Calculate the magnitude of its acceleration when it has moved s = 10m in ml sec².

In order to go from her office to her favorite pizzeria for lunch, woman walks due east (polar angle of 0°) at an average speed of 3.2 m/s for 5 minutes and then walks due north (polar angle of 90 degrees ) for 4 minutes at average speed of 2.7 m/s . (c) what is the average velocity for her trip? (magnitude & direction) (d) if the woman has one hour for lunch and she gets back from the pizzeria just in time, what was the average velocity for her entire lunch trip?
