Explanation:
The conversion factor from miles per hour to kilometers per hour is 1.609344.
Hence;
To convert 75mi/h to kilometers per hour,
75mi/h * 1.609344 = 120.7 kilometers per hour
b)
To convert 75mi/h to feet per second
Since
1 mile per hour = 1.46667 foot per second
75mi/h = 75 * 1.46667 = 110 feet per second
- Angle (θ) = 60°
- Force (F) = 20 N
- Distance (s) = 200 m
- Therefore, work done
- = Fs Cos θ
- = (20 × 200 × Cos 60°) J
- = (20 × 200 × 1/2) J
- = (20 × 100) J
- = 2000 J
