As an apple tree is transported by a truck moving to the right witha constant velocity, one of its apples shakes loose and falls towardthe bed of the truck. Of the curves shown in Figure CQ3.13, (i)which best describes the path followed by the apple as seen by astationary observer on the ground, who observes the truck mov-ing from his left to his right? (ii) Which best describes the pathas seen by an observer sitting in the truck?Figure CQ3.13

(i) For a stationary observer on ground, the apple acquires the horizontal velocity due to the…

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.
An athlete crosses a 29 m wide river by swimming perpendicular to the water current at a speed of 1.1 m/s relative to the water. He reaches the opposite side at a distance 45 m downstream from his starting point. w = 29 md = 45 mvs = 1.1 m/s Part (a) How fast is the water in the river flowing with respect to the ground in m/s? Part (b) What is the speed of the swimmer with respect to a friend at rest on the ground in m/s?

Solve the following problem using analytical techniques: Suppose you walk 18.0 m straight west and then 25.0 m straight north. How far are you from your starting point, and what is the compass direction of a line connecting your starting point to your final position? (If you represent the two legs of the walk as vector displacements A and B, as in Figure 3.58, then this problem asks you to find their sum R=A+B.)
Dr. L. and his cat Kepler are coming home from fishing. They ended their trip on the southbank of a 1200 m wide river, directly across from where Caroline is waiting to pick them upon the north bank. They are in identical boats that travel at 4 m/s (VB) on still water. Theriver is normally ‘lazy’ and flows with negligible velocity. On a calm day, if they pointed theboats north, they would cross the river in exactly 300s. However, today, the river is flowingdue east with a constant velocity (VW) of 1 m/s relative to the ground. Kepler, because shedoesn’t know better (she is a cat after all), has not taken this into account. Without payingattention, Kepler keeps the boat pointed due north for the entire trip. A) Relative to the ground, what is Kepler’s velocity? Derive an algebraic solution(in terms of VB and VW only) and then give a numerical answer (three significant figures isfine) expressed in degrees relative to due north (e.g. ‘42.3° west of north’).

Airplanes A and B are flying with constant velocity in the same vertical plane at angles 30° and 60° with respect to the horizontal respectively as shown in figure. The speed of A is 100/3 m/s. At time t = Os , an observer in y – axis finds B at a distance of 500 m .This observer sees B moving with a constant velocity perpendicular to the line of motion of A If at t = to , A just escapes being hit by B , to in seconds is, B -30°
Agent Tim, flying horizontally at a constant 350 km/h in a low-flying helicopter, wants to drop a small explosive onto a master criminal's automobile which is traveling at a constant 225 km/h on a level highway 95.0 m below. At what distance behind the automobile should Agent Tim be when the bomb is released? Include a complete diagram of the situation.
