4. If two objects travel through space along two curves, it's often important to know whether they will collide. (Will a missile hit its moving target? Will two aircraft collide?) The curves might intersect, but we need to know whether the objects are in the same position at the same time. Suppose the following vector functions represent the trajectories of two particles. Do these particles collide? If not, do their paths intersect? (Assume t≥ 0.) (a) r₁(t) = (t², 7t 12, t²) and r₂(t) = (4t-3, t², 5t - 6) (b) p₁(t) = ti+t²j+t³k and p2(t) = (1 + 2t)i + (1 + 6t)j + (1 + 14t)k

1. A pilot in a small plane encounters shifting winds. He flies 26.0 kmkm northeast, then 45.0 kmkm due north. From this point, he flies an additional distance in an unknown direction, only to find himself at a small airstrip that his map shows to be 70.0 kmkm directly north of his starting point. What was the length of the third leg of his trip? What was the direction of the third leg of his trip? 2. A boat can travel 7.3 m/s in still water. It is crossing a 220 m wide river while pointed due east and the river is flowing at 3.7 m/s, north. What is the speed of the boat, relative to the shore? How long does it take to cross the river?

A wise elder duck finally realizes that the solution is to fly at an angle to the wind. If the ducks can fly at 15 m/sm/s relative to the…
A projectile is launched with an initial velocity of v0 and an elevation angle of zero degrees.

Both the time of flight and the range would be larger on Mars. b. Both the time of flight and the range would be larger on Earth. c. The time of flight is greater on Earth but the range would be greater on Mars. d. The time of flight is greater on Mars but the range would be greater on Earth. e. The time of flight and the range would be the same on both planets.

How far from the east edge of the nest did the mouse fall, in centimeters?
A student standing on a cliff throws a stone from a vertical height d=8.0m above the level ground with velocity v0=16.2m/s at an angle θ=34∘ below the horizontal. It moves without air resistance. Use a Cartesian coordinate system with the origin at the stone's initial position. 1).With what speed, in meters per second, does the stone strike the ground? 2) which option is correct If the stone had been thrown from the clifftop with the same initial speed and the same angle, but above the horizontal, then compare their impact velocities. The impact velocity when throwing a stone above horizontal will be more than the case when throwing a stone below horizontal. The impact velocities of the two situations will be the same. More information is needed to conclude the relative strength of impact velocities. The impact velocity when throwing a stone above horizontal will be less than the case when throwing a stone below horizontal.
A train travels due south at 32 m/s (relative to the ground) ina rain that is blown toward the south by the wind. The path of each raindrop makes an angle of 65° with the vertical, as measured by an observer stationary on the ground. An observer on the train, however, sees the drops fall perfectly vertically. Determine the speed of the raindrops relative to the ground. Number Units
