Q1 8 Points A particle of constant mass m moves along the x-axis. Its velocity v and position x satisfy the 1 1 equation: 2 -m (12 - v8 ) = k (x - x2) , where k, vo and To are constants. 2 Show that whenever v * 0, m - -kx. dt Please select file(s) Select file(s) Save AnswerQ2 8 Points A particle moves along the curve f (x ) = 27 sin . As the particle passes through the 2 point 3 , its -coordinate increases at a rate of v 10 centimeters per second. How fast is the distance from the particle to the origin changing at this instant?
