Question

distance travelled by stone falling down from towel in 8 sec if t is 8sec a is 10m/s​

Answer 1

Answer:

The distance travelled by stone is 320 m.

Explanation:

Given data:

• Acceleration due to gravity (g) = 10 m/s²
• Time taken (t) = 8 s
• Initial velocity (u) = 0

To find:

Distance travelled by the stone.

Solution:

We know that,

S = ut + 1/2at²

By substituting the values, we get

⟹ S = 0 × u + 1/2 × 10 × 64

⟹ S = 0 + 320

= 320 m.

Answer 2

We have,

Time = 8 s

Acceleration due to gravity = 10 m/s²

Initial velocity = 0 m/s (rest)

We know,

h = ut + ½ gt² (S = ut + ½ at²)

⇒ h = ½ gt²

⇒ h = ½ × 10 m/s² × (8 s)²

⇒ h = 5 m/s² × 64 s² = 64 × 5 m

⇒ h = 320 m (answer).

More:-

In these type of questions, we substitute,

• g instead of a
• h instead of S.

So that the equations become,

1. v = u + gt
2. h = ut + ½ gt²
3. 2gh = v² - u².
