Question

pls solve this physics questions​

Answer 1

speed for 1 round:

$(2\pi \: r )\div 40 \times 40$

so

$\pi \: r \div 800$

for time: 140 sec

dist is,

$0.175\pi \: r$

this is nearly 2 roundss ..

option b

Answer 2

Answer:

Hi friend!!

Explanation:

2 min 20 second = 140 second.

he completed one round in 40 second.

in 140 second, he will cover= 140/40=3.5 round.

after 3.5 round, he would be on the opposite side of the starting point.

So the displacement will be the diameter or 2 round

(Option b)

Hope it will help you!!❣️❣️❣️❣️
