Answer:
v = 15.19 m/s
Explanation:
As we know that when object is dropped from some height then initial speed of the object is taken as
[tex]v_i = 0[/tex]
now for the final speed of object we can say that if acceleration is constant then the final speed will be given by kinematics equation
[tex]v_f = v_i + at[/tex]
here we have
[tex]a = 9.8 m/s^2[/tex] (due to gravity)
now from this equation of motion
[tex]v_f = 0 + (9.8)(1.55)[/tex]
[tex]v_f = 15.19 m/s[/tex]
Answer:
-15.2
Explanation:
the guy above didn't put a negative when talking about gravity which is always -9.80
