a train travelling at 100km/h slows down with a uniform decceleration of 0.600 m/s^2. How long does it take to stop?
Use the following to solve your problem:
V²=U²+2AS,
WHERE V=FINAL VELOCITY
U=INITIAL VELOCITY
A=ACCELERATION
S=DISTANCE OF ACCELERATION
Hint: Fial velocity=0, solve for S. A is negative in this case.
