Answer:
5.76 m/s
Explanation:
Applying,
S = d/t............... Equation 1
Where S = speed, d = distance, t = time.
For circular motion,
d = 2πr............ Equation 2
Where r = radius of the circular track, π = pie
Substitute equation 2 into equation 1
S = 2πr/t.............. Equation 3
From the question,
Given: r = 110 m, t = 2 minutes = (2×60) = 120 s
Constant: π = 3.14
Substitute these values into equation 3
S = (2×3.14×110/120)
S = 690.8/120
S = 5.76 m/s
