The figure gives the acceleration of a 3.0 kg particle as an applied force moves it from rest along an x axis from x = 0 to x = 9.0 m. The scale of the figure's vertical axis is set by as = 9.0 m/s2. How much work has the force done on the particle when the particle reaches (a) x = 4.0 m, (b) x = 7.0 m, and (c) x = 9.0 m? What is the particle's speed and direction (give positive answer if the particle moves along x axis in positive direction and negative otherwise) of travel when it reaches (d) x = 4.0 m, (e) x = 7.0 m, and (f) x = 9.0 m? a (m/s2) 6 8 x (m) (a) Number Units (b) Number Units (c) Number Units (d) Number Units (e) Number UnitsCurrent Attempt in Progress A single force acts on a 3.3 kg particle-like object in such a way that the position of the object as a function of time is given by x = 2.5t - 5.0t2 + 3.1+3, with x in meters and t in seconds. Find the work done on the object by the force from t = 0 to t = 3.4 s. Number UnitsCurrent Attempt in Progress An elevator cab has a mass of 4510 kg and can carry a maximum load of 1910 kg. If the cab is moving upward at full load at 4.00 m/s, what power is required of the force moving the cab to maintain that speed? Number n Units V
