a = -1.16m/s^2

Explanation:

Given

Initial speed u = 2.5 m/s

Final speed v = 0

Distance traveled S = 7.7 m

Duration t = 2.0 s

Solution

Distance traveled before the wheel got stuck

$d = ut\\\\d= 2.5 \times 2\\\\d = 5 m$

Distance traveled after wheel got stuck

$S' = S - d\\\\S' = 7.7-5\\\\S' = 2.7 m$

Acceleration

$v^2 = u^2 + 2as'\\\\0 = 2.5^2 + 2 \times a times 2.7\\\\a = -1.16m/s^2$
