Question

a rubber ball is dropped from a height of 5m

Answer 1

a Rubber Ball is Dropped From a Height of 5m.

Initial Velocity = 0

Final Velocity = ?

Gravitational Acceleration = 10ms^-2

From Third Equation of Motion

v^2 = u^2 + 2as

v^2 = 0 + 2 × 10 × 5

v^2 = 100

v = √100 = 10ms^-1.

Hence,The Velocity with which it will hit the ground is 10ms^-1.

Answer 2

Answer:

a Rubber Ball is Dropped From a Height of 5m.

Initial Velocity = 0

Final Velocity = ?

Gravitational Acceleration = 10ms^-2

From Third Equation of Motion

v^2 = u^2 + 2as

v^2 = 0 + 2 × 10 × 5

v^2 = 100

v = √100 = 10ms^-1.
