Homework Statement
A world's land speed record was set by Colonel John P. Stapp when in March 1954 he rode a rocket-propelled sled that moved along a track at 1020 km/h. He and the sled were brought to a stop in 1.4 s. In g units, what acceleration did he experience while stopping?
Homework Equations
I think I am supposed to use the constant acceleration equation
v = v(0) + at
1 g unit = 9.8m/s^2
The Attempt at a Solution
You only get two attempts to get it right. My first attempt was 1239.06 g units but it was wrong. My second time around i got -1239.06 g units but i was just wondering if anyone could double check it. Thanks in advance.
