Question

A car moves a circular path of radius 20m in 50s with a uniform speed. Find the speed

Answer 1

we know that

speed = distance travelled / time taken

here,

distance travelled = circumference of the circle = 2Ï€r

so,

v = 2Ï€r / t

as

r = 20m

t = 50s

so,

v = (2 × 3.14 × 20) / 50

thus,

the uniform speed will be

v = 2.512 m/s
