Two particles A and B start from rest at the origin s = 0 and move along a straight line such that aA = (6t-3)ft/s2 and aB = (12t2-8)ft/s2, where t is in seconds. Determine the distance between them when t = 4 s and the total distance each has traveled in t = 4 s.
Effect of pressure on temperature and density of air for an adiabatic process, The pressure is to be raised from atmospheric to 7 psi (4.83 bar). The process is adiabatic, and the volume is constant and unknown.
This problem came from the "kinematics of particles" part holding the "Determination of the motion of a particle" section, so use the formula relating to this section of this part.
Evaluate the maximum height reached by the sphere, and the distance traveled by the block.
a man of mass m1 walks along a plank of length l with a constant acceleration a relative to the plank. The mass of the plank is m2 and the coefficient of friction between the plank and the ground is mu. Find the distance the plank moves if the man..
Derive the operational transfer function and the sinusoidal transfer function for an RC high-pass filter. Plot the step response and the complete frequency response (magnitude and phase).
block c starts from rest and moves downward with a constant acceleration. knowing that after 5 s the velocity of block a relative to block d is 8 ft/s, determine a) the acceleration of the block c. b) the acceleration of portion e of the cable.
