A scooter weighing 150 g together with its rider moving at 36 km/hr is to take a turn of radius 30 m. What horizontal force on the scooter is needed to make the turn possible?

Explanation

To solve the problem of determining the horizontal force needed for a scooter weighing 150 kg (including the rider) to make a turn of radius 30 m while moving at a speed of 36 km/h, we can follow these steps:

### Step 1: Convert the speed from km/h to m/s
The speed of the scooter is given as 36 km/h. To convert this to meters per second (m/s), we use the conversion factor:
\[ 1 \text{ km/h} = \frac{5}{18} \text{ m/s} \]
Thus,
