Question

if we drop an object, its initial velocity is zero. How far will it fall in time?​

Answer 1

Answer:

4.9t^2

Explanation:

S=1/2gt^2

S=5t^2

Answer 2

If we drop an object, its initial velocity is zero it will fall 4.9t² m in time.

Given:

Initial velocity of object is zero.

To Find:

How far will it fall in time.

Solution:

When the object is dropped, given that the initial velocity is zero:

• After the object has left contact with whatever threw it, the object is in free-fall.
• Under these circumstances, the motion is one-dimensional and has gravitational acceleration of magnitude g which is 9.8 m/s².

Now, using the second equation of motion which is:

$s = ut + \frac{1}{2} at^{2}$

where, u = initial velocity

t = time take

a = acceleration

s = distance covered

$s = 0*t + \frac{1}{2} gt^{2}$

$s = \frac{1}{2} (9.8)t^{2}$

s = 4.9t² units

Therefore, if we drop an object, its initial velocity is zero it will fall 4.9t² m in time.
