Questions Related to collisions
A ball of mass $m _{1}$ is moving with velocity $v$. It collides head on elastically with a stationary ball of mass $m _{2}$. The velocity of ball becomes $\dfrac{v}{3}$ after collision, then the value of the ratio $\dfrac{m _{2}}{m _{1}}$ is:
A ball of mass m moving with velocity v collides elastically with another ball of identical mass coming from the opposite direction with velocity 2v. Their velocities after collision are :
A sphere $'P'$ of mass $'m'$ moving with velocity $'u'$ collides head-on with another sphere $'Q'$ of mass $'m'$ which is at rest. The ratio of final velocity of $'Q'$ to initial velocity of $'P'$ is
($e =$ coefficient of restitution)
If two balls each of mass 0.06 kg moving in opposite directions with speed of $4\, m\, s^{-4}$ collide and rebound with same speed, then the impulse imparted to each ball due to other is:
A ball of mass '$M$' moving with a velocity $\overrightarrow{V}$ collides head on elastically with another body of the same mass '$M$' moving with a velocity $-\overrightarrow{V}$ in the opposite direction. After the collision :
A heavy steel ball of mass greater than 1 kg moving with a speed of 2m/ s collides head on with a stationary ping pong ball of mass less than 0.1 g. The collision is elastic. After the collision the ping pong ball moves approximately with a speed
Consider the following statements A and B. Identify the correct choice in the given answer
A : In a one - dimensional perfectly elastic collision between two moving bodies of equal masses, the bodies merely exchange their velocities after collision
B : If a lighter body at rest suffers perfectly elastic collision with a very heavy body moving with a certain velocity, after collision both travel with same velocity
Consider the following statements A and B and identify the correct answer:
$A :$ In an elastic collision, if a body suffers a head on collision with another of same mass at rest, the first body comes to rest while the other starts moving with the velocity of the first one.
$B :$ Two bodies of equal masses suffering a head-on elastic collision merely exchanges their velocities.
In one - dimensional head on collision, the relative velocity of approach before collision is equal to :
A body of mass 'm' moving with certain velocity collides with another identical body at rest. If the collision is perfectly elastic and after the collision, if both the bodies move, they can move
