Question

You toss a ball at 30 m/s straight upwards. How much time will take the ball to reach the top of its path?​

Answer 1

Step-by-step explanation:

One thing we need to remember is that at the max height of parabolic motion, the velocity is 0 (because the object has to stop for a millisecond in the air to turn around and head back down). Use the one-dimensional motion equation

v = v₀ + at and filling in:

0 = 30 + (-9.8)(t) and

-30 = -9.8t so

t = 3 seconds
