H equals -4.9t2 plus 20t plus 10 How many seconds will it take for the stone to hit the ground h equals 0 after it is thrown in the air?
We have to trust the equation you give us, telling us that the acceleration of gravity is 9.8,the tossing speed is 20 straight up, and the stone leaves your hand from 10 aboveground.If all of that is true, then H = -4.9 t2 + 20t + 10, and when the stone hits the ground,-4.9 t2 + 20t + 10 = 0Multiply both sides of the equation by -1 :4.9 t2 - 20t - 10 = 0We're not going to be able to factor that ugly thing,so we have to use the quadratic equation:t = [ 20 +/- sqrt(400 + 196) ] / 9.8 = ( 20 +/- 24.413) / 9.8I get 4.532 seconds (rounded)
How do you diffentiate y equals 3.5 minus 3.5 times the Exp minus 1 over 20t?
y(t) = 3.5 - 3.5*e1-20t Then dy/dt = -3.5*e1-20t*(-20) = 70*e1-20t
