Question

a horse is tied with a 2m long rope at a pole. what distance will the horse run around the pole with a rope tightly stretched, if it takes and one a half rounds? also find the displacement of the horse

Answer 1

Answer: Total distance = 4π meters and the Total Displacement = 0

Explanation: 1.5 rounds around the pole = 1.5 times the circumference of the circle form by the rope.

Circumference of a Circle = 2πr

from the question the radius = 2m, hence the total circumference = 2π*2 = 4π meters.

Displacement which is distance between initial position and final position. When the horse takes one and a half rounds around the pole, it ends up back at the starting point. Hence, the displacement is zero.
