Explanation / Answer

Here ,

a) u = 0 cm/s

v = 27.2 cm/s

d = 1.96 cm

let the acceleration of the blood is a

Using third equation of motion

v^2 - u^2 = 2 * a * d

27.2^2 - 0^2 = 2 * 1.96 * a

a = 188.7 cm/s^2

the acceleration is 188.7 cm/s^2

b)

time taken = v/t

time taken = 27.2/(188.7)

time taken = 0.144 s

the time taken is 0.144 s
