A rocket is launched from a height of 3m with an initial velocity of 15 m/s at what time will the rocket be 13m from the ground? First person to answer gets brainliest

Step-by-step explanation:

To find time required by rocket to reach 13m, we need to first find time required for 10m :

Using Equation of motion :

10 = 15 * t - 5t^2

5t^2 - 15t + 10 = 0

t^2 - 3t + 2 = 0

t = 1 and 2

Therefore, rocket will reach 13m from ground in 1 sec.

1: -2 3/4, -2 1/2, -14, 0, 3, 8 1/3

2: -4, -3, -2 1/2, -2 1/4, 3 1/4,
