Solving for the time it will take for the object to hit the ground:
- Plug in the initial velocity in the "Vot" spot. You don't have to worry about the starting height "Ho" because it is 0. Then solve for "t". You should get 2 values.
Solving for the maximum height of the object:
- For the maximum height you take the two values for "t" that you got and find the sum. Then divide the sum by 2 because you had to values. Then with that value you will solve for the maximum height or h(t) by plugging it into "t". The number you get when you solve it will be the maximum height.
Word Problems with Velocity and Maximum Height
By Justin Schwarz and Dylan JonesStart off with the formula:
h(t)=-16t+Vot+Ho
Solving for the time it will take for the object to hit the ground:
- Plug in the initial velocity in the "Vot" spot. You don't have to worry about the starting height "Ho" because it is 0. Then solve for "t". You should get 2 values.
Solving for the maximum height of the object:
- For the maximum height you take the two values for "t" that you got and find the sum. Then divide the sum by 2 because you had to values. Then with that value you will solve for the maximum height or h(t) by plugging it into "t". The number you get when you solve it will be the maximum height.
Keep in mind:
You can NOT have a negative as an answer!
