Question

a body initially at rest has an acceleration 2cm/s². What will be the velocity 5 seconds after the start

please answer as soon as possible​

Answer 1

Answer: initial velocity , u = 0                                                                                                    

              acceleration , a = 2m^-2                                                                                              

               time , t = 5s                                                                                                      

              distance traveled , s = ut + 1/2 at^2                                                                    

                s = [ 0 * 5 ] + [ 1/2 * 2 * 5^2 ]

                    = 25 m

Answer 2

Answer:

v-u/t

initial position =2 cm

final position = 0 cm

time taken = 5 s

= 2-0/5

=2/5 = 0.4 cm / s square
