Final answer:
The acceleration of a body moving with uniform velocity is zero. To convert 50 km/hr into m/s, use the conversion formula: 1 km/hr = 0.2778 m/s. Therefore, 50 km/hr is equal to 13.89 m/s.
Step-by-step explanation:
The acceleration of a body moving with uniform velocity is zero. When an object is moving with uniform velocity, it means it is moving at a constant speed and in a straight line. In this case, there is no change in velocity, so the acceleration is zero.
To convert 50 km/hr into m/s, we can use the conversion formula:
1 km/hr = 0.2778 m/s
Therefore, 50 km/hr is equal to 50 × 0.2778 m/s = 13.89 m/s.
