Question

two bodies of mass 100 kg and 2kg are dropped freely from same height find the ratio of time to reach the ground ,answer fastly ​

Answer 1

Answer:

1:1

Explanation:

For this, we can use v = u +- gt or h = ut +- (1/2)gt^2

Now observe that neither of the formulae involve the mass of the body.

Now, in either cases, u = 0 , g = 9.8 ms^-1 , h1 = h2 .

Therefore, v1 = v2

              ⇒v1/v2 = 1 : 1

Answer 2

Answer: 1:1

Explanation:

Since,

          v = u - gt &

          h = ut - 1/2gt^2

Now,

        We observe that neither of the formula involve the mass of the body.

Since,

         u = 0 ;

         g = 9.8 m/s ;

         h1=h2

Therefore,

                 v1 = v2

=> v1/v2 = 1:1
