A car falls off a ledge and drops to the ground in `0.5 s`. let` g=10 m//s^(2)` (for simplifyng the calculation).
(i) what is its speed on striking the ground ?

what is its average speed during 0.5s?
(iii) How high is the ledge from the ground ?

Explanation

To solve the problem step by step, we will address each part of the question sequentially.

### Given Data:
- Time of fall, \( t = 0.5 \, \text{s} \)
- Acceleration due to gravity, \( g = 10 \, \text{m/s}^2 \)
- Initial velocity, \( u = 0 \, \text{m/s} \) (since the car starts from rest)

### (i) Finding the speed on striking the ground:
