We can find final velocity using the equation as follows:
<span>vf = vi + g*t </span>
<span>Substituting our known values for vi and g we obtain: </span>
<span>vf = vi + g*t </span> <span>vf = 0 + (9.8)*(1.5) [ 1.5 s since it is the time it </span><span>take to reach the top and to fall back) </span> <span>vf = 14.7 = 15m/s</span>
<span>We can find the distance traveled using </span>
<span>d = vi*t + 1/2g*t^2 </span>
<span>Substituting our values for vi, g and t we get </span>
Multiply 56 / 1 and 4 / 5. This will result in 224 / 5. You can divide it to result in 44.8, or keep it the fraction because it cannot be simplified any further.
