A stone is dropped from the top of a tower and it strike with 3km/hr, ...
Explanation:
Initial Velocity:
When the first stone is dropped from the top of the tower, it has an initial velocity of 0 km/hr as it starts from rest.
When the second stone is thrown vertically downwards from the same top of the tower, it has an initial velocity of 4 km/hr downwards.
Acceleration:
Both the stones experience the same acceleration due to gravity, which is approximately 9.8 m/s².
Final Velocity of First Stone:
The first stone is dropped from rest and falls freely under the influence of gravity. The final velocity of the stone when it strikes the ground is given as 3 km/hr.
Final Velocity of Second Stone:
We can find the final velocity of the second stone using the equation:
v² = u² + 2as
Where,
v = final velocity
u = initial velocity
a = acceleration due to gravity
s = distance travelled
Initial velocity of the second stone, u = 4 km/hr downwards
Distance travelled by the stone, s = height of the tower
Let's assume that the height of the tower is h metres. Then the distance travelled by the stone is also equal to h metres.
Now, substituting the values in the above equation, we get:
v² = (4 km/hr)² + 2(-9.8 m/s²)(h m)
v² = 16 + (-19.6h)
v² = -19.6h + 16
v² = -19.6(h - 16/19.6)
v = sqrt[-19.6(h - 16/19.6)]
Therefore, the final velocity of the second stone when it strikes the ground depends on the height of the tower.
Conclusion:
Thus, we can conclude that the final velocity of the first stone is 3 km/hr and the final velocity of the second stone depends on the height of the tower.
