Question

On a hot summer day, a young girl swings on a rope above the local swimming hole (Figure 1) . When she lets go of the rope her initial velocity is 2.30m/s at an angle of 35.0 ∘ above the horizontal. If she is in flight for 0.611s , how high above the water was she when she let go of the rope

Answer 1

you should think that the girl first goes up then falls back, because there is an angle. That angle makes a vertical component of the velocity. Then you should use velocity equations.
