1.	A cyclist completes full round of a circular track of radius 318 m in 1.5 min, Find its speed and velocity? Plz answer this in steps, it would help me a lot
Answer» Given: A cyclist completes full round of a circular TRACK of radius 318 m in 1.5 min. To find: SPEED and Velocity of cyclist. Calculation: Speed is DEFINED as the total distance divided by the time TAKEN to cover that distance. $\rm{speed = \dfrac{distance}{time} }$ $= > \rm{speed = \dfrac{2\pi r}{t} }$ $= > \rm{speed = \dfrac{2\pi (318)}{1.5 \times 60} }$ $\boxed{ = > \rm{speed = 22.2 \: m {s}^{ - 1} }}$ Velocity is defined as the total Displacement divided by the time taken to cover the specific Displacement. Here Displacement is zero , because the cyclist starts and stops at the same point. $\rm{velocity = \dfrac{displacement}{time} }$ $= > \rm{velocity = \dfrac{0}{1.5 \times 60} }$ $\boxed{ = > \rm{velocity = 0 \: m {s}^{ - 1} }}$ Hope It Helps.
