Retardation applied by brakes is 2.5 m/s²
Acceleration (a) applied by brakes will be -2.5 m/s²
v = u + at
0 = u + (-2.5 m/s² × 10 s)
u = 25 m/s
Initial velocity of car was 25 m/s
Acceleration (a) applied by brakes will be -2.5 m/s²
v = u + at
0 = u + (-2.5 m/s² × 10 s)
u = 25 m/s
Initial velocity of car was 25 m/s

Equation of motion
V= U+aT
V= 0
T=10s
V= U+aT
V= 0
T=10s
