At the instant under consideration, the hydraulic cylinder AB has a length L = 0.75 m, and this length is momentarily increasing at a constant rate of 0.2 m∕s. If vA = 0.6 m∕s and ? = 35°, find the rate of change of the length L in m/s, in order for the velocity of the slider B to be 0.15 m/s.
The system shown in figure has a rightward velocity of 3 m/sec. Determine its velocity after 5 seconds. Take u = 0.2 for the surfaces in contact. Assume pulleys frictionless.
A cesium-ion engine for deep-space propulsion is designed to produce a constant thrust of 2.0N for long periods of time. If the engine
is to propel a 71-Mg spacecraft on an interplanetary mission, compute the time t required for a speed increase from 40 000 km/h to 69
000 km/h. Also find the distance s traveled during this interval. Assume that the spacecraft is moving in a remote region of space where
the thrust from its ion engine is the only force acting on the spacecraft in the direction of its motion.
