A particle inoves along the x-axis. It's position as a function of time is given by z (t)t+22- The following questions refer to that situation. Only consider times t greater than or equal to zero fno negative values of t. Note application of the derivative is finding the maximo and minima of functions. O 1m 0 2m D Question 7 1 pts For times t between t- 0 and t 3 s, what is the minimum value of x attained...

A particle poves along the x-axis. It's position as a function of time is given by z (t) =-31+ 2e-翅 The following questions refer to that situation. Only consider times t greater than or equal to zero (no negative values of t). Note Some of the questions ask about the maximum velocity attained, or the maximum x coordinate, etc. Hint: use calculus! A very important application of the derivative is finding the maxima and minima of functions 1 pts D...
Particle 1 has mass 3.42 kg and its position in meters as a function of time is given by r1(t) = 2.00t i + 7.00t2j. Particle 2 has mass 5.00 kg and its position in meters as a function of time is given by r2(t) = 7.00 i - 8.00t3j.
