Question

An insect moves along a circular path of radius 10 cm with a constant speed. if it takes 1 minutes to move from a point on the path to a diametrically opposite point find :
(a) distance covered
(b) speed covered
(c) displacement
(d) velocity ?

Answer 1

given, r=10cm then half of circumference =3.14×10= 31.4 &time=1min =60sec
(a) distance= half of circumference=31.4
(b) speed =31.4/60= 0.52m/sec
(c) displacement = 31.4 also
(d) velocity also 0.52

hope...... it's ryt!!!!!
