Show that if the net force on a particle constrained to move in 1 dimension depends only on position, f-f), the newton's second law can be solved to find v as a function ofx given by: 1 dv2 2 dx v2-si +副0f(x')dx'. note: use the chain rule: dt- = 2dte b) consider a mass constrained to move along x-axis and subject to a net force f =-kx, where k > 0 is a constant. the mass is released form rest at x xo at t-0. use the equation for velocity from part a) to find (x) = . separate the variables and integrate to obtain the time dependence of the position of this mass. hint: when solving the awkward integral you will obtain, use first the suband then ucos 0 in subsequent integral. dt dx dt dx

The scalar triple product computes the magnitude m of the moment of a force vector f about a specified line. it is m = (r × f) · n, where r is the position vector from the line to the point of application of the force and n is a unit vector in the direction of the line. use matlab to compute the magnitude m for the case where f = [12, −5, 4] n, r = [−3, 5, 2] m, and n = [6, 5, −7].
