Get started for freeA particle undergoes three successive displacements in a plane, as follows:, 4.00 m southwest; then , 5.00 m east; and finally , 6.00 m in a direction north of east. Choose a coordinate system with the y axis pointing north and the x axis pointing east. What are (a) the x component and (b) the y component of ? What are (c) the x component and (d) the y component of ? What are (e) the component and (f) the y component of ? Next, consider the net displacement of the particle for the three successive displacements. What are (g) the x component, (h) the y component, (i) the magnitude, and ( j) the direction of the net displacement? If the particle is to return directly to the starting point, (k) how far and (l) in what direction should it move?
Vector is in the negative direction of a y axis, and vector is in the positive direction of an x axis. What are the directions of (a) and (b) ? What are the magnitudes of products (c) and (d) ? What is the direction of the vector resulting from (e) and (f)? What is the magnitude of the vector product in (g) part (e) and (h) part (f)? What are the (i) magnitude and (j) direction of?
The x component of vector is -25.02 m and the y component is +40.0 m. (a) What is the magnitude of ? (b) What is the angle between the direction of and the positive direction of x?
Equation 3-2 shows that the addition of two vectorsis commutative. Does that mean subtraction is commutative, so that?
A person desires to reach a point that isfrom her present location and in a direction that isnorth of east. However, she must travel along streets that are oriented either north–south or east–west. What is the minimum distance she could travel to reach her destination?
