Question

find time taken by particle to come rest if a declaration of value is applied on a particle for 12m initial velocity of particle is 12m/s​

Answer 1

Answer:

v = 0

u = 12 m/s

s = 12 m

${v}^{2} - {u}^{2} = 2as$

0 - 144 = 2a(12)

a = - 144/24

a = - 6 m/s2

a = v - u / t

- 6 = - 12/t

t = 2 sec
