Kinematics Question 510

Question: A large number of bullets are fired in all directions with same speed v . What is the maximum area on the ground on which these bullets will spread

Options:

A) πv2g

B) πv4g2

C) π2v4g2

D) π2v2g2

Show Answer

Answer:

Correct Answer: B

Solution:

Area in which bullet will spread = πr2

For maximum area, r=Rmax=v2g[when θ=45]

Maximum area π Rmax2=π(v2g)2=πv4g2
