An object is displaced from its start point by distance in some direction. Does this completely specify a displacement vector?
Homework Answers
Yes it represents a displacement vector, because the the distance from the start point indicates the magnitude of the displacement vector and it is some direction from start point. So all these information about the displacement vector. It is completely specify the displacement vector.

If an object on a horizontal frictionless surface is attached to a spring, displaced, and then released, it will oscillate. If it is displaced a distance 0.126 mm from its equilibrium position and released with zero initial speed. Then after a time 0.791 ss its displacement is found to be a distance 0.126 mm on the opposite side, and it has passed the equilibrium position once during this interval. Find the amplitude. Find the period. Find the frequency.

If an object on a horizontal, frictionless surface is attached to a spring, displaced, and then released, it will oscillate. If it is displaced 0.170 m from its equilibrium position and released with zero initial speed, then after 1.450 s its displacement is found to be 0.170 m on the opposite side, and it has passed the equilibrium position once during this interval. (a) Find the amplitude. m (b) Find the period. s (c) Find the frequency. Hz

Problem 11.25 If an object on a horizontal frictionless surface is attached to a spring, displaced, and then released, it oscillates. Suppose it is displaced 0.128 m from its equilibrium position and released with zero initial speed. After 0.830 s , its displacement is found to be 0.128 m on the opposite side and it has passed the equilibrium position once during this interval. Part A Find the amplitude of the motion.

1.How does the buoyant force determined from the mass of the fluid displaced compare with the difference in the dry and wet weights of each object? Is Archimedes' priciple verified? 2.How does the density determined for each object compare with its accepted value? You will have to look up the densities of Al, Cu, and Pb. Note : Discuss with the percent error

An object moves in a circular path with constant angular speed. Compare the direction of the object's tangential velocity vector to its centripetal acceleration vector. A) Both vectors point in the same direction B) The vectors point in opposite directions C) The vectors are perpendicular D) Impossible. The acceleration is zero. Two objects with masses m1 and m2 are original a distance r apart. The magnitude of the gravitational force between them is F. if BOTH masses are doubled, and...
