Need Help? Read It 6. [0/5.55 Points] DETAILS PREVIOUS ANSWERS SERPSE10 2.5.OP.010. MY NOTES An object moves along the x axis according to the equation x = 3.85t² - 2.00t + 3.00, where x is in meters and t is in seconds. (a) Determine the average speed between t = 1.50 s and t = 3.10 s. m/s (b) Determine the instantaneous speed at t = 1.50 s. 8.5 X We are given an explicit expression for x as a function of time. Calculus methods can be used to determine the velocity as a function of time. m/s Determine the instantaneous speed at t = 3.10 s. m/s (c) Determine the average acceleration between t = 1.50 s and t = 3.10 s. m/s² (d) Determine the instantaneous acceleration at t = 1.50 s. m/s² Determine the instantaneous acceleration at t = 3.10 s. m/s² (e) At what time is the object at rest? 3 X The instantaneous velocity will be zero when the object is at rest. Take the derivative of x(t) to find v(t). s Need Help? Read It Watch It Watch It PRACTICE ANOTHER
