Answer:

Step-by-step explanation:

The formula for KE is

KE=(1)/(2)mv^2 We have everything we need to solve for the velocity, but we first have to convert the mass from grams to kg:

450 g = .450 kg

8.8=(1)/(2)(.450)v^2 and we'll rearrange that and solve it for v before we do any math:

$v=\sqrt{(2(8.8))/(.450) }$ so

v = 6.3 m/s rounded to the correct number of sig fig's
