A particle of mass m is constrained to move along the x-axis and is subjected to a force given by . Assuming the particle had an initial velocity of Vo and was at the origin at t = 0, find an equation for the particle's velocity and set up the integral from which the position equation as a function of time could be determined. NOTE: You do not need to evaluate the integral for the position as a function of...

A 8.56 kg box is constrained to move only along a frictionless x-axis. The box is at rest at the origin when variable force F acts on the mass; the diagram is a graph showing how the force changes with distance. Find the final speed of the mass, in m/s, after it has moved 7 m.
The velocity of a particle constrained to move along the x-axis as a function of time t is given by: v(t)=−(18/t0)sin(t/t0). Part A If the particle is at x=1 m when t=0, what is its position at t = 7t0. You will not need the value of t0 to solve any part of this problem. If it is bothering you, feel free to set t0=1 everywhere. Part B Denote instantaneous acceleration of this particle by a(t). Evaluate the expression 1...
