A motor car running at the rate of `7ms^(1)` can be stooped by applying brakes in `10m` Show that total resistance to the motion when brakes are on is one fourth of the weight of the car .

Explanation

To solve the problem, we need to find the total resistance to the motion of a motor car that stops from a speed of 7 m/s in a distance of 10 m. We will use the equations of motion to derive the required result.

### Step-by-Step Solution:

1. **Identify Given Data:**
- Initial velocity (U) = 7 m/s
- Final velocity (V) = 0 m/s (since the car stops)
- Distance (S) = 10 m
