Explanation / Answer

Given,

u = 0 m/s ; v = 27.2 cm/s ;

a)D = 1.96 cm

We know from eqn of motion

v^2 = u^2 + 2 a S

27.2^2 = 0^2 + 2 x a x 1.96

a = 739.84/3.92 = 188.73 cm/s^2

Hence, a = 188.73 cm/s^2

b)we know that

v = u + at

27.2 = 0 + 188.73 t

t = 27.2/188.73 = 0.144 s

Hence, t = 0.144 s
