Question

(URGENT) A ball rolls off a ledge. Its velocity is 7.70m/s in a horizontal direction. It falls on the floor 1.60m below the ledge. What is the horizontal distance that it travels while in the air?

Answer 1

the horizontal distance is 4.355 meters

Step-by-step explanation:

The computation of the horizontal distance while travelling in the air is shown below:

Data provided in the question is as follows

Velocity = u = 7.70 m/s

H = 1.60 m

R = horizontal direction

Based on the above information

As we know that

R = u × time

where,

Time =
`\sqrt{(2H)/(g) }`

So,

=
`7.70* \sqrt{(2* 1.60)/(10) }`

= 4.355 meters

hence, the horizontal distance is 4.355 meters
