Detailed explanation-1: -Explanation: Unit of speed is meter/ second hence the answer is (a) 5 m/s.
Detailed explanation-2: -Distance is represented in metre (m) and time in second (s), so speed become m/s.
Detailed explanation-3: -In this article, some of the most popular physics symbols are mentioned. It is interesting to note that some physics symbols are very relatable (like “d” for distance) while some are unrelatable (like “c” for the speed of light).
Detailed explanation-4: -Speed gets the symbol v (italic) and velocity gets the symbol v (boldface). Average values get a bar over the symbol. Displacement is measured along the shortest path between two points and its magnitude is always less than or equal to the distance.
Detailed explanation-5: -Therefore, velocity is expressed in metres/second or m/s. The SI unit of velocity is metre per second (m/s).
