Starting with the original equation,
h=−16t2+vt+k, in order to get v in terms of the other variables,
−16t2 and
k need to be subtracted from each side.
This yields
vt=h+16t2−k, which when divided by t will give v in terms of the other variables.
However, the equation
v= is not one of the options, so the right side needs to be further simplified.
Another way to write the previous equation is
v=+, which can be simplified to
v=+16tChoices A, B, and C are incorrect and may be the result of arithmetic errors when rewriting the original equation to express v in terms of
h,t, and
k.
