A body is dropped from a certain height h and second body is thrown do

1.	A body is dropped from a certain height h and second body is thrown downward with velocity of 5m/s simultaneously .what will be difference in heights of the two bodies after 3s ?
Answer» We will use the FOLLOWING equation of motion. S = Ut + 0.5gt² Where S is the height, g the gravitational acceleration and t the TIME and U the initial velocity. In the first case U = 0and hence S is : S = 0 + 0. 5 × 10 × 9 = 45m In the second case U is 5m/s and hence height is : S = 3 × 5 + 0.5 × 10 × 9 S = 60M The difference in height is thus : 60 - 45 = 15m

Answer»

We will use the FOLLOWING equation of motion.

S = Ut + 0.5gt²

Where S is the height, g the gravitational acceleration and t the TIME and U the initial velocity.

In the first case U = 0and hence S is :

S = 0 + 0. 5 × 10 × 9 = 45m

In the second case U is 5m/s and hence height is :

S = 3 × 5 + 0.5 × 10 × 9

S = 60M

The difference in height is thus :

60 - 45 = 15m
