Question

Find distance and displacement when a body completes 2 1/2 rounds in a square field of side 5m. * Please say me very urgent

Answer 1

Answer:

Distance = 50 metres

Displacement = 7.07 metres

Explanation:

Given :

• 2 ½ rounds were completed around a square of side 5 metres

To find :

• Distance and Displacement at the end of 2 ½ rounds

Perimeter of the square field = 4×5 = 20 metres

Distance = 5/2 ×20

Distance = 50 metres

The distance travelled by the object is equal to 50 metres

At the end of 2½ rounds the object would be equal to diametrically opposite point of the starting point

Displacement²=5²+5²

Displacement²=25+25

Displacement²=50

Displacement = 7.07 metres

The distance is equal to 50 metres and Displacement is 7.07 metres
