The acceleration is constant and negative. The average velocity is The x-component of E ” cancels the x-component of. The fourth displacement D ” and its components are sketched in Figure 1. In all cases, the negative acceleration indicates an acceleration to the left. Use xv t to find xv at each t.

One vector and the sum are given; find the second vector universiatria and direction. Use the constant acceleration equations to find 0xv and. The magnitude of the displacement is much less than the distance traveled along the path. The vector first line plus the vector arrow gives the vector for the second line. B ” is the force universiyaria biceps exerts. The sign of the velocity and of the acceleration indicate their direction.

When they have opposite sign the speed is decreasing. You should head 8.

Apply the constant acceleration kinematic equations. A ” The eastward component of B ” must be km larger than the magnitude of the westward component of. The graph is not a straight line, so the acceleration is not constant.


The sum of the force displacements must be zero. The average acceleration depends on the chosen time interval.

Take the beginning of the journey as the origin, with north being the y-direction, east the x-direction, and the z-axis vertical. Let A ” be the displacement km at For the interval between 0 and 53 s, 2 sd Find the components of the weight force, using the specified coordinate directions.

One force and the vector sum are given; find the second force. The four displacements add to zero. Take your tent’s position as the origin.

The spider speeds up for the first 5 s, since xv and xa are both positive. 112

The curvature is positive so xa is positive. The velocity reaches zero at 40 s. For part c Find the vector sum of the four displacements. It is initially positive, decreases to zero, and then becomes negative with increasing magnitude.

The velocity is zero at 20 s, positive for 15 s to 20 s, and negative for 20 universjtaria to 25 s.

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. If the velocity direction is positive, then the acceleration is positive. The slope of the graph of xv versus t decreases as t increases.


The situation is sketched in Figure 2. This is consistent with an average acceleration that decreases in magnitude during each successive time interval. It is useful to show xRyR and R ” on a sketch, so we can specify what angle we are computing.

While xa is also positive the speed increases and while xa is negative the speed decreases. Vectors A “B “and C ” 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.

In part b the speed decreases so the acceleration is in the direction opposite to the direction of the velocity. If both tents were due east of yours, the distance between them would be The turtle initially moves farther away from the origin searw then stops and moves in the -direction.
