Answer:-/22346
Step-by-step explanation:
To calculate the time it takes for the penny to hit the ground, we use the formula given relating time and the height of the penny. We calculate as follows:
h = 4.9 (t²) + v0 t + h o
150 = 4.9 (t²) + 0 t + 0
0 = 4.9 (t²) - 150
t = 5.53
t = -5.53
Since in reality there is no time that is negative, the answer would be 5.53 units of time.
