Hey guys, I'm confused on this problem: It is a typical sunny day. Assume your reaction
time is 0.50 s and the acceleration of your car is –8.2 m/s2. What is the no-skid stopping distance when the car’s speed is initially 26.9 m/s?
a=-8.2 m/s^2
v0=26.9 m/s
v=0
t=0.50s
d=?
d=v0(t) +1/2a(t^2)
v^2=v0^2+2ad
So I tried using the v^2=v0^2+2ad and got 44.12 m. However, the answer is 57.57. What did I do wrong? Thanks!
