Question

How deep is a valley if it takes a rock 5.2 seconds to strike the bottom and it is traveling at 25 m/s?

Answer 1

The valley is 130 m deep.

Explanation:

Formula we use,

→ Height = Time × Speed

Now the height will be,

→ Time × Speed

→ 5.2 × 25

→ 130 metres

Thus, valley is 130 m deep.

Answer 2

`\huge\boxed{\sf h = 130\ m}`

Explanation:

Given data:

Time = t = 5.2 s

Velocity = v = 25 m/s

Required:

Height = h = ?

Formula:

h = vt

Solution:

h = 25(5.2)

h = 130 m

`\rule[225]{225}{2}`
