We know that a= vf-vi/t
a= acceleration= 3.09 m/s^2 vf=final velocity= 14.5 m/s vi= initial velocity= ? ; t= time = 2.81 s
so
3.09= 14.5-vi/2.81
vi=5.817 m/s = 5.82 m/s

A car moves with a constant acceleration of 3.6 m/s2. At a time of 5 s, it is 110 m beyond a mile marker; at a time of 8 s, it has a velocity of 10 m/s. Find the car's position after the mile marker at time 8 s.
a V 43.3 m/s2 s. This answer agrees with the one obtained above using Equation [1]. Guided Problem A race car starting from rest accelerates at a constant rate of 5.20 m/s?. After how much time has the car traveled 28.5 m along the x-axis? Part 1 of 6 Identify the known and unknown quantities. The car starts from rest so its initial velocity is vo 0. During the time interval of interest, the car travels 28.5 m at constant...

3. During a very quick stop, a car decelerates at 6.2 m/s2. Assume the forward motion of the car corresponds to a positive direction for the rotation of the tires (and that they do not slip on the pavement). a. What is the angular acceleration of its tires in rad/s2, assuming they have a radius of 0.28 m and do not slip on the pavement? b. How many revolutions do the tires make before coming to rest, given their initial...
