Question

Ted throws an object into the air with an initial vertical velocity of 54 feet per second from a platform that is 40 feet above the ground. About how long will it take the object to hit the ground? show steps please.

Answer 1

the verticle motion formula: h = -16t² + vt + s where t = time, v = initial velocity and s = initial height

h = -16t² + vt + s
0 = -16t² + 54t + 40 You will need to use the quadratic formula to solve this

I'll attach the solution and steps
