The body is thrown upward at an initial speed of 17 meters per second. Determine the maximum height of the body.

The body is thrown upward at an initial speed of 17 meters per second. Determine the maximum height of the body. Determine the time to reach the maximum height.

1. According to the formula:
h = (V ^ 2-Vo ^ 2) / 2a
We find the height by substituting the values of acceleration and speed
Because our movement is equally slow, the acceleration will be with a minus sign
It turns out:
h = (0 ^ 2-17 ^ 2) / 2 * (- 10) = (0-289) / (- 20) = (- 289) / (- 20) = 289/20 = 14.45 (m)
2.T.k. we now know the height, we from the formula
h = ((Vo + V) / 2) * t
Displaying time
t = h * 2 / (Vo + V)
Now we plug in the values and find the time
t = 14.45 * 2 / (17 + 0) = 28.9 / 17 = 1.7 (c)
Answer:
h = 14.45 (m)
t = 1.7 (c)
