For sport, a 12 kgarmadillo runs onto a large pond of level, frictionless ice. The armadillo鈥檚 initial velocity is 5.0 m/salong the positive direction of an xaxis. Take its initial position on the ice as being the origin. It slips over the ice while being pushed by a wind with a force of 17 Nin the positive direction of the yaxis. In unit-vector notation, what are the animal鈥檚 (a) velocity and (b) position vectors when it has slid for 3.0 s?
The high-speed winds around a tornado can drive projectiles into trees, building walls, and even metal traffic signs. In a laboratory simulation, a standard wood toothpick was shot by pneumatic gun into an oak branch. The toothpick鈥檚 mass was , its speed before entering the branch was , and its penetration depth was role="math" localid="1657007959021" . If its speed was decreased at a uniform rate, what was the magnitude of the force of the branch on the toothpick?
A certain particle has a weight of at a point where. localid="1656143387519" What are its:(a) weight and (b) mass at a point where localid="1656143411696" ? What are its (c) weight and(d) mass if it is moved to a point in space where ?
Figure 5-22 shows overhead views of four situations in which forces act on a block that lies on a frictionless floor. If the force magnitudes are chosen properly, in which situations is it possible that the block is
(a) stationary and
(b) moving with a constant velocity?
In Fig. 5-64, a forceof magnitudeis applied to a FedEx box of mass . The force is directed up a plane tilted by .The box is connected by a cord to a UPS box of mass on the floor. The floor, plane, and pulley are frictionless, and the masses of the pulley and cord are negligible. What is the tension in the cord?
