Name: See: PHY111/211 Pre Laboratory Problems: Elastic Collisions 1. Two particles, each with a mass of 0.44K9 collide. One particle was stationary. particle has a speed of 0.5 m/s at an angle r(40e above the axis or v-0.5 m/s 400 What is (a) the magnitude of the moving particle's momentum, (b) its x-component of momentum and (c) its y component of morreitum? Hint:mi·P,-" After a perfectly elastic collision the moving 2. The stationary particle involved in the collision of Problem #1 has a speed of 0 418 ms at angle of-50 or v 0.418 m/s 2-50° after the collision. What is (a) the magnitude of the stationary of momentum? ifyou comparethe y components for problem #1 and #2 they should be equal and opposite. This will not be the case in the experiment because the collision is not perfectly elastic.) particle's momentum, (b) its x-component of momentum and (c) its y-component 3. Use the information of problem #1 and #2 to find the momentum of the moving particle before the collision. Hint: Use the conservation of momentum.

Explanation / Answer

We know that, momentum of a moving particle is.

P=mv where m is the mass of the object and V is the velocity.

So,

P=0.44*0.5

P=0.22 kg-m/s

Now x component will be

Pcos40 and y component will be Psin40

X component.. 0.22cos40=0.168

Y component 0.22sin40=0.141
