Concept explainers

Centripetal Force

A particle, body, object or certain mass while travelling in a rotational path or semicircular path, experiences an inertia force. If that inertia force pulls the towards the inward of the imaginary circle in the rotation, it is termed as centripetal force.

A landscape architect is planning an artificial waterfall in a city park. Water flowing at 1.70 m/s will leave the end of a horizontal channel at the top of a vertical wall h = 2.35 m high, and from there it will fall into a pool (Fig. P3.42). (a) Will the space behind the waterfall be wide enough for a pedestrian walkway? (b) To sell her plan to the city council, the architect wants to build a model to standard scale, which is one-twelfth actual size. How fast should the water flow in the channel in the model?

Two trains, one traveling at 72.0 km/h and the other at 144 km/h, are headed toward one another along a straight, level track. When they are 1.100x103 m apart, each engineer sees the other’s train and applies the brakes. This causes each train to have an acceleration against the train’s direction of motion with the magnitude of 1.00 m/s2.. a) Calculate the distance required for each train to come to a complete stop and based on this result conclude whether there will be a collision? b) Calculate the time required for each train to come to a stop.

In his novel From the Earth to the Moon (1865), JulesVerne describes a spaceship that is blasted out of a cannon, calledthe Columbiad, with a speed of 12,000 yards>s. The Columbiad is900 ft long, but part of it is packed with explosives, so the spaceship accelerates over a distance of only 700 ft. Estimate the acceleration experienced by the occupants of the spaceship duringlaunch. Give your answer in m>s2. (Verne realized that the “travelers would . . . encounter a violent recoil,” but he probably didn’tknow that people generally lose consciousness if they experienceaccelerations greater than about 7g ∙ 70 m>s2.)

Assume you are driving a car at a constant speed of 76 km/h. Suddenly you see a deer standing on the highway and you must put on the brakes. Your reaction time (time elapsed between the moment you see the deer and your foot hitting the brakes) is 0.118 s. The brakes provide an acceleration with a magnitude of 4 m/s2, and a direction opposite the initial velocity. How do you find the total distance traveled?
Suppose you drop a rock into a dark well and, using precision equipment, you measure the time for the sound of a splash to return.

(b) Now calculate the distance taking into account the time for sound to travel up the well. The speed of sound is 332.00 m/s in this well.
