Question

Suppose that an object is dropped from a height of h meters and hits the ground with a velocity of v meters per second. Then =v19.6h. If an object is dropped from a height of 17.2 meters, with what velocity does it hit the ground?

Answer 1

Explanation:

According to the formula given, we have:

v = √(19.6 * h)

where h = 17.2 meters

Substituting the value of h in the equation, we get:

v = √(19.6 * 17.2) meters/second

Simplifying this expression, we have:

v = √(335.52) meters/second

v ≈ 18.3 meters/second (rounded to one decimal place)

Therefore, the object hits the ground with a velocity of approximately 18.3 meters per second.
