One force and the vector sum are given; find the second force.

Fisica Universitaria 12va. Edicion Sears, Zemansky Vol. 2

The magnitude of the total displacement is: If the velocity direction is positive, then the universitwria is positive. Apply the constant acceleration kinematic equations. Call the displacements A “B “C ” and D “where D ” is the final unknown displacement for the return from the treasure to the oak tree.

A ” The eastward component of B ” must be km larger than the magnitude of the westward component of. Find the components of the weight force, using the specified coordinate directions. Find the vector sum of the four displacements.

In part b the speed decreases so the acceleration is in the direction opposite to the direction of fiscia velocity. Vectors A “B “and C ” are sketched in Figure 1. The velocity is zero at 20 s, positive for 15 s to 20 s, and negative for 20 s to 25 s.

The graph is not a straight line, so the acceleration is not constant. This is consistent with an average acceleration that decreases in magnitude during each successive time interval. B ” The resultant upward force is less than the aears component of ,B ” so yE must be downward.

The x-component of E ” cancels the x-component of. For part c The average acceleration depends on the chosen time interval. Let A ” be the displacement km at When they have opposite sign the speed is decreasing. The curvature is positive so xa is positive.

The slope of the graph of xv versus t decreases as t increases. If both tents were univsrsitaria east of yours, the distance between them would be The final displacement D ” from this diagram agrees with the vector D ” calculated in part a using components.

The velocity reaches zero at 40 s. The fourth displacement D ” and its components are sketched in Figure 1.

If the velocity direction is positive then the acceleration is negative, and if the velocity direction is negative then the acceleration direction is positive. The situation is sketched in Figure 2. The southward component of B ” cancels the northward component of. universitarix

You should head 8. When seqrs and xv have the same sign the speed is increasing. The sum of the force displacements must be zero.

B ” is the force the biceps exerts. Take your tent’s position as the origin. The four displacements add to zero.

Use the constant acceleration equations to find 0xv and. The spider speeds up for the first 5 s, since xv and xa are both positive. The average velocity is The vector first line plus the vector arrow gives the vector for the second line.
