Question

An object falls freely from rest the total distance covered by it in 2s will be​

Answer 1

Answer:

Distance, S = 19.6 meters

Explanation:

Given the following data;

Time = 2 seconds

We know that acceleration due to gravity is equal to 9.8 m/s².

Also, the initial velocity of the object is equal to zero because it's starting from rest.

To find the total distance covered by the object, we would use the second equation of motion;

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

Where;

• S represents the displacement or height measured in meters.
• u represents the initial velocity measured in meters per seconds.
• t represents the time measured in seconds.
• a represents acceleration measured in meters per seconds square.

Substituting into the equation, we have;

$S = 0*2 + \frac {1}{2}*(9.8)*2^{2}$

$S = 0 + 4.9*4$

$S = 4.9*4$

Distance, S = 19.6 meters

Therefore, the total distance covered by the object is 19.6 meters.
