Question

Two blocks each of masses 100g and 250g having the same size are dropped simultaneously from 81m and

100m respectively. Find the ratio of time they would take in reaching the ground. Will the ratio remain same

if (i) one of the objects is hollow and other one is solid and (ii) both of them are hollow, size remaining the

same in each case? Give reason.​

Answer 1

Answer:

it is the question of kinematics it means it dont with the cause of the motion and it only depends on the height therefore

81 = 1/2 x 10 x t^2

81/5 = t^2

4.02 sec = t1

for the other block the displacement is 100

then

100 = 1/2 x 10 x t^2

100/5 = t^2

4.4 sec = t2
