body cover a circular path of radius R in 20 seconds calculate distance and displacement by the end of 70 seconds
Answers
Answer:
DISTANCE = 3.5 × circumference of the cirle
DISPLACEMENT = 2 × radius
Step-by-step explanation:
total distance traveled in 20 sec is = 1 times of the circle. then in 70 sec it will be = 3.5 × circumference of the circle
DISPLACEMENT is the shortest distance covered that will be in this case- diameter of the circle e.s
2×r
Answer:
displacement=2R
Distance=5πR
Step-by-step explanation:
distance covered in 20 seconds =2πR
distance covered in 70 seconds =(1/2+3)2πR
=5/2x2πR
=5πR
Displacement in 1 round = 0
no. of rounds in 70 seconds =3 complete rounds and a half round
the displacement of 3 complete rounds would be equal to 0 whereas the displacement of the half round would be equal to the diameter of the circle
D=2R
Therefore the Displacement=2R
