Question

HC Verma class 9 gravitation related question​

Answer 1

By laws of motion,

Gloves downward motion,

Height = Initial velocity Time + 1/2 * *

Gravity Time^2 Initial velocity = 0

Hence,

Height = 1/2* Gravity * Time^2

Gravity = 9.8 m/s

Height = 4.9 Time^2

Ball upward motion,

Initial velocity = 40

Hence,

40 - Height = 40 * 1/2 * 9.8 * Time^2

Solving for Time,

Time = 1 s

Then,

We get,

Height = 4.9 m

The meeting height = 40 - 4.9

The meeting height = 35.1 m

Hence, The glove will meet the ball at 35.1 m above the ground after 1 s.
