Ahiker travels 1.0 kilometer south, turns and travels 3.0 kilometers west, and then turns and travels 3.0 kilometers north. what is the magnitude of the total displacement traveled by the hiker

Total Displacement (D) = 5.0 km

Explanation:

Displacement is said to be the distance between the starting point of a subject to the finishing point. Displacement look into the shortest distance rather than the path taken. From the question; we were told that:

A hiker travels 1.0 kilometer south and then travels 3.0 kilometers west,

At this point, he will be 2.0 km west of his starting point.

Afterwards, he then turns and travels 3.0 kilometers north (finishing point)

Therefore; The magnitude of the total Displacement (D) = starting point + Finishing point.

Total Displacement (D) = (2.0 + 3.0) km

Total Displacement (D) = 5.0 km

the speed of the cart after 3 seconds of low fan speed is ⇒ 54.0 cm/s.

the speed of the cart after 5 seconds of medium fan speed is ⇒ 120.0 cm/s.

the speed of the cart after 2 seconds of high fan speed is ⇒ 64.0 cm/s.
