A ship’s wheel is rotated 128 degrees. Its radius is 22 cm. How far would a point on the wheel’s edge move in this rotation?
ZanzabumX [31]
To solve this problem, we use this formula:
s = rθ

where
s is the arc length or in this case, the distance traveled by a point of a wheel
r is the radius of the circle or the wheel
θ is the subtended angle or the angle of rotation of the wheel

Plugging in the given values and converting degrees to radians
s = 22 *128 (π/180)
s = 49.15 cm

A racehorse is running with a uniform speed of 69 km/hr along a straightaway. What is the time it takes for the horse to cover 4
Tomtit [17]

Answer:

21 seconds

Explanation:

First, convert km/hr to m/s.

69 km/hr × (1000 m / km) × (1 hr / 3600 s) = 19.2 m/s

Distance = rate × time

400 m = 19.2 m/s × t

t = 20.9 s

Rounded to two significant figures, it takes the horse 21 seconds.
