Explanation:
The computation of speed will the alpha particle have after the collision is shown below:-
In a perfectly elastic the kinetic energy and collision the momentum are considered.
The velocity of the particles defines the below equation:
As we know that
Here, we consider A is the alpha particle and B is the proton and now by the above values we can solve the equation which is below:-
Therefore the correct answer is
Answer:
Explanation:
Given
mass m collides elastically with floor and jump to its original height I .e.velocity of rebound is same as the initial velocity
Impulse imparted by steel ball to the ground is given by the change in momentum of steel ball
and impulse is product of average force and time
so we need time to calculate the average force. So, option e is correct
