Question

a car is traveling in a straight line and decelerating at a constant rate. after 3.2 seconds it has traveled 88m and slowed to a speed of 27 m/s what is the initial speed i got 52 m/s

Answer 1

s=ut +1/2 *(a t^2)
88=u*3.2-(a/2)*3.2*3.2.......................1
v=u+at
27=u-a*3.2.....................2
multiply equation 2 with 1.6 and eliminate a and find out u (intial velocity)
i got u=28

Answer 2

i got 28 too
