Given:
Vf = 0 m/s
Vi = 4 m/s
t = 25.0 s
Determine the acceleration.
Formula for acceleration:
a = ( vf - vi )/t
a = acceleration
vf = final velocity
vi = initial velocity
t =time
Solution:
Subsitute the given values of final velocity, initial velocity and time to the formula for acceleration.
a = ( vf - vi )/t
a = ( 0 m/s - 4 m/s )/25 s
a = ( -4 m/s ) / 25s
a = - 0.16 m/s^2
Final answer:
a = - 0.16 m/s^2
