Question

1. A. Suddenly, the matrix causes a whale and a potted plant to fall side by side from the sky. The mass of the whale is 3 x 108kg while the mass of the potted plant is 5kg. Both of them have a velocity of 1.3 x 104m/s right before they hit the ground. Which one has a greater impulse assuming the impact causes both to be at rest?

B. What is conserved in an elastic collision? Give one example of such a phenomena

C. Which type of collision has the greatest loss in energy?What is a special characteristic of such a collision?

D. What is the most common type of collision observed in real life situations?

Answer #1

impulse ; I = F.dt =ΔP = m* (vf- vi )

since both have same speed before the hit and after hit zero so
more mass means more impulse so **the
whale has a greater impulse**

B

What is conserved in an elastic collision

1) momentum

2) energy

exmaple => collision of billiard ball,the collision between the atoms

C.perfectly inelastic collision has the greatest loss in energy

in this type of collision object deformed completely after collision

example => cars, airlines, trains accident

D.

an inelastic collision is the most common type of collision observed in real-life situations

because there is always the loss of energy in collision
