The velocity,v of a missile is related to time t, By the equation v=5t^2+3t+1.calculate the time at which the velocity is minimu

Cloud [144]

Answer:

time: t = -0.3
minimum: v = 0.55

Step-by-step explanation:

For quadratic ax^2 + bx + c, the extreme value is found at x=-b/(2a). For your quadratic, the minimum is found at ...

t = -(3)/(2(5))

t = -0.3 . . . . . time of minimum velocity

The value of velocity at that time is ...

v = 5(-0.3)^2 +3(-0.3) +1 = 5(.09) -.9 +1

v = 0.55 . . . . . value of minimum velocity
