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 = 7.0 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?

The figure below gives spring force Fx versus position x for the spring–block arrangement of the second figure. ?
The scale is set by Fs = 200 N. We release the block at x = 16.0 cm. How much work does the spring do on the block when the block moves from xi = +9.0 cm to (a) x = +5.0 cm, (b) x = -5.0 cm, (c) x = -9.0 cm, and (d) x = -11.0 cm?

The father speeds up by 1.4 m/s and then has the same kinetic energy as the son. What are the original speeds of (a) the father and (b) the son?
2 AnswersPhysics1 year agoonly two forces act on a 2.7 kg object that moves with an acceleration of 3.5 m/s2 in the positive direction of a y-axis.?
if one of the forces acts in the positive direction of an x-axis and has a magnitude of 8.5 N, what is the magnitude of the other force?

There are two forces on the 1.59 kg box in the overhead view of the figure but only one is shown. For F1 =22.2 N, a = 11.8 m/s2, and θ=33.5°?
find the second force (a) in unit-vector notation and as (b) a magnitude and (c) a direction. (State the direction as a negative angle measured from the +x direction.)
