Ethan throws a ball into the air from a cliff that is 152.4 m high with an initial velocity of 4 m/s. How long does it take for the ball to hit the ground?

Respuesta :

38.1 seconds I believe simply divide 4m/s into 152.4 m and you will have 38.1 seconds
 Use the formula that gives height in meters: h = –4.9t2 + v0t + h0. Substitute in the given values and solve.

I hope this helps; if it does please mark brainliest
