Ameasuring tape drops from a roof that is 16 feet above the ground. after how many seconds does the measuring tape land on the ground? how would you write the equation?

It takes 1 second for the tape to reach the ground.

Equation to use:

As explain above, the initial position s 16 ft, there is no initial velocity, so , and the acceleration of gravity is 32 ft/s^2, and should be considered negative [as pointing down in the y-direction], so the equation simplifies to:

In order to find the tima it takes it to hit the ground, we simple solve the equation for t when y(t) = 0 (the tape has reached the ground (zero height in the y-direction):

We select the positive time (+1 second) which is what makes physical sense, since a negative value in time would mean time before the tape was dropped.

So the answer is: It takes 1 second for the tape to reach the ground.

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.
