Question

A body covers on revolution around a circular park of circumference 176m un 4 mins.find the displacement of the body after 6 mins

Answer 1

$\huge\underline{\underline{\mathfrak\red{Answer}}}$

Distance travelled in 4 min = 176m

Distance travelled in 4 min = 176mDistance travelled in 1 min = 176/4 m

Distance travelled in 6 min

Distance travelled in 6 min= 6 × 176/4 m

Distance travelled in 6 min= 6 × 176/4 m= 264 m = 1 revolution + 1/2 revolution

So, displacement

= 1/2 revolution

= 176/2

= 88m

So, displacement of body after 6 min = 88m !!

Answer 2

Answer:

The displacement is 56 meter (after 6 mins)

Explanation:

Solution :

Circumference of circular park = 176m

1 revolution completed = 4 minutes

1.5 revolution will be completed = 6 minutes

distance = 176 m

time = 4 minutes

Speed Formula :

speed = distance covered by the body / time taken

176 / 4

44 meter/ min

distance covered in 1 minute is 44 m

Now,

Find the distance covered in 6 minutes

So,

6 minutes = 44 × 6 = 264

Total distance of circular track = 176 m

Circumference = 176 m

diameter = C / π

⇒ 176 / (22/7)

⇒ 56

Therefore,

The displacement is 56 meter (after 6 mins)
