Question

a body starts sliding over a horizontal surface with an initial velocity of 0.5 m per s. Find its speed after 2 secs it was stopped?​

Answer 1

Answer:

first equation of motion is used in this question.

v=u+at

0=0.5+2*a

-0.5/2= a

multiply left side by 10, we get

-5/20=a

-1/4=a

a=-0.25
