The position-time graph above represents the motion of a remote-controlled toy
truck as it moves back and forth along a straight line. The origin marks the
position of the boy who controls the truck. The boy has not yet learned how to
make the truck change its direction.
A positive position marks positions to the right of the boy, and a negative
position marks positions to the left of the boy,
1. During which time intervals is the truck to the right of the boy? 10 - 95 S
To the left of the boy?
2. During which time intervals is the truck moving in the positive direction?
In the negative direction?
Not moving?
3. What is the position of the truck at 0 seconds? -4 15 seconds? 6
30 seconds? 45 45 seconds? - a

Part a determine the magnitude of the x component of f using scalar notation. fx f x = nothing lb request answer part b determine the magnitude of the y component of f using scalar notation. fy f y = nothing lb request answer part c determine the magnitude of the z component of f using scalar notation. fz f z = nothing lb request answer provide feedback figure1 of 1a force vector acting on a ring attached to the ground is shown in the xyz space together with its x, y, and z components lying on the corresponding positive axes. the ring is located at the origin. force f is located in the first octant. f makes an angle of 60 degrees with its x component and an angle of 45 degrees with its y component. a force vector acting on a ring attached to the ground is shown in the xyz space together with its x, y, and z components lying on the corresponding positive axes. the ring is located at the origin. force f is located in the first octant. f makes an angle of 60 degrees with its x component and an angle of 45 degrees with its y component.

What is the measure of a change in an objects velocity?

What are two different ways you could find the value of a? explain these methods.
