Q. 1) A car traveling at a speed of vo = 60 m/s stops smoothly (that is, its deceleration is constant) over a distance of d = 167m.

i) What is its acceleration during the time it is stopping?
ii) How long (what amount of time) does it take for the car to come to a stop?
iii) After the car has gone 1/3 of the stopping distance, what is its speed?
iv) If the car had been going 10m/s but had stopped in the same d = 167m distance, what would its acceleration have been?

2) The left ventricle of the heart accelerates blood from rest to a velocity of +26 cm/s.

i) If the displacement of the blood during the acceleration is 2cm, decide the acceleration.
ii) How much time does it take the blood to reach its final velocity?
