question 22 of 24. you drop a water balloon from a second - story window. which formula would you use to calculate the velocity of the water balloon just before it hits the ground, assuming it is in free fall? a. g = v/t b. v = gt c. v = g/t d. t = v/g

question 22 of 24. you drop a water balloon from a second - story window. which formula would you use to calculate the velocity of the water balloon just before it hits the ground, assuming it is in free fall? a. g = v/t b. v = gt c. v = g/t d. t = v/g

Answer

Explanation:

Step1: Identify free fall velocity formula

In free fall (initial velocity ( u=0 )), velocity ( v ) is given by ( v = gt ), where ( g ) is gravitational acceleration and ( t ) is time.

Step2: Evaluate options

Option A (( g=vt )) rearranges to ( v=g/t ), incorrect (velocity increases with ( t )). Option B (( v=gt )) matches the free fall velocity formula. Option C (( v=g/t )) is wrong (velocity ∝ ( t )). Option D (( t=√s )) is not a valid free fall time formula (correct: ( t=√(2s/g) )).

Answer:

B. v = gt
