When the firecracker hits the ground, H(t) = 0.0 = -16t^2 + 90t + 160 Using the quadratic formula,t = (-90 +- sqrt(90^2 - 4(-16)(160))) / 2(-16)t = -1.42 ort = 7.04
The negative time is extraneous. Therefore,t = 7.04 s.
Seven Seconds is your answer!
2.3 meters per second = 7.546 feet per second
Formula: multiply the value in meters per second by the conversion factor '3.2808398950087'.
So, 2.3 meters per second = 2.3 × 3.2808398950087 = 7.54593175852 feet per second.
