Answer:
B
Step-by-step explanation:
The trick you need to employ is that when the rock hits the ground, the timer stops. So h must be taken as 0.
0 = - 16t^2 + 255 Set up the equation
- 255 = - 16t^2 Divide by -16
15.9375 = t^2 Switch
t^2 = 15.9375 Take the square root of both sides.
sqrt(t^2) = sqrt(15.9375)
t = 3.992 seconds
The closest answer is B
Answer:
1, 81, and 121 are correct
