I got a physics question.

Question

A person throws a baseball from a height of 7 feet with and initial vertical velocity of 50 feet per second. Use the vertical motion model, h=-16t²+vt+s , where v is the initial velocity in feet per second and s is the height in feet, to calculate the amount of time the baseball is in air before it hits the ground. Round your answer to the nearest tenth if necessary. Time in air:______seconds

Answer 1

Plug all the values into the equation. The coordinate system is selected so the ball hits the ground when h=0. The units all mesh in that h is in ft, v in ft/s, acceleration due to gravity is in ft/s² (implied, but not stated in the problem)

You now have an equation that looks like 0 = at² + bt + c Solve for t using the quadratic formula and throw out the negative answer. (a, b, and c here are the usual coefficients in a quadratic)

This looks more like a problem a math teacher would ask. (using feet, no significant digits, and odd labeling for the equation)

Good luck!
