Question

12. An object starts from rest and has a displacement s-4t It has a uniform acceleration of 8m/s The velocity of the body at t=2s is​

Answer 1

Answer:

16 m/s

Step-by-step explanation:

intial velocity (u) = 0

final velocity (v) = ?

acceleration = 8 m/s

disp= s-4t

time =2 second

by formula

v=u+at

v=0+(8*2)

v=16m/s
