If we consider the boy and the car as a system, then the impulsive force caused by traction of the shoes is internal to the system. For car B Ans. This material is protected under all copyright laws as they currently exist. Cartons having a mass of are required to move along the assembly line with a constant speed of Determine the smallest radius of curvature,for the conveyor so the cartons do not slip.
The horizontal component of the relative velocity of the boy with respect to the car A is. The flight path of a jet aircraft as it takes off is defined by the parametric equations and where is the time after take-off, measured in seconds, and and are given in meters. If he lands on the second flat cardetermine the final speed of both cars after the motion.
The vertical component of initial velocity and the initial vertical position are. The horizontal component of velocity is and the initial horizontal position is.
Since the velocity is always directed along the tangent dinaica the path and the acceleration is directed downward, then tangential and normal components of acceleration are Ans. Initially, the spring has been compressed and the elastic potential energy is. The man A has a weight of and. The boy jumps off the flat car at with a velocity of relative to the car as shown. The vertical component of velocity when is given by The magnitude and direction angle when are Ans. The coefficients of static and kinetic friction between a carton and the conveyor are and respectively.
Thus, the horizontal component of the velocity of the boy is  Conservation of Linear Momentum: Therefore, they will cancel out. No portion of this material may be reproduced, in any form or by any means, without permission in writing from the publisher.

When platform P r.cc.hibbeler at a height of s above the datum, its initial gravitational potential energy is 60s. When the man falls from a height of 8 ft above the datum, his initial gravitational potential energy is. If the plane starts to level off at determine at this instant a the horizontal distance it is from the airport, b its altitude, c its speed, and d the magnitude of its acceleration.
A small metal particle travels downward through a fluid medium while being subjected to the attraction of a magnetic field such that its position is where is in seconds. When platform P stops momentary, the spring has been compressed to its maximum and the elastic potential energy at this instant is.

As the result, the linear momentum is conserved along x axis. For car A  Solving Eqs. Whenits horizontal position is given by Ans. The datum is set at the initial position of platform P.
