Answer:
a)
b)
And we can use the quadratic formula to solve it:
And since the time can't be negative the correct option would be
Step-by-step explanation:
For this case we can use the following kinematics formulas:
For this case we assume that the only acceleration is the gravity a = g =9.8 m/s^2. And for this case we can assume that the reference point is and the final height would be
since is below the initial point.
Teh acceleration would be a=-g, since the gravity is acting dowward, we assume that the initial velocity is 0, so then we have everything to replace and we got:
And solving for t we got:
For the second part assuming that We have an initial vertical speed of we have the following equation:
And we have this quadratic equation:
And we can use the quadratic formula to solve it:
And since the time can't be negative the correct option would be
