Question

two stones A and B are dropped from a multistoried building stone is dropped from hundred metre height and after some time stone b is dropped from 50 both reaches the earth at same time will they have equal velocity​

Answer 1

Answer:

Step-by-step explanation:

For the stone A, height h = 100 m, g = 10 m/s 2

Velocity on reaching the ground is, v 2 = u 2 + 2as

=> v 2 = 0 + 2(10)(100)

=> v = 44.7 m/s

For the stone B, height h = 50 m, g = 10 m/s 2

Velocity on reaching the ground is, v 2 = u 2 + 2as

=> v 2 = 0 + 2(10)(50)

=> v = 31.6 m/s

Thus, the velocities of the stone are not same when they reach the ground.

Answer 2

Answer:

Step-by-step explanation:

For the stone A, height h = 100 m, g = 10 m/s 2

Velocity on reaching the ground is, v 2 = u 2 + 2as

=> v 2 = 0 + 2(10)(100)

=> v = 44.7 m/s

For the stone B, height h = 50 m, g = 10 m/s 2

Velocity on reaching the ground is, v 2 = u 2 + 2as

=> v 2 = 0 + 2(10)(50)

=> v = 31.6 m/s

Thus, the velocities of the stone are not same when they reach the ground.
