Question

   A 0.060 kg tennis ball, moving with a speedof 4.50m/s, has a head-on collision with a 0.090 kg ball initiallymoving in the same direction at a speed of 3.00m/s. Assuming a perfectly elastic collison, determine the speed anddirection of each ball after the collision?    A 0.060 kg tennis ball, moving with a speedof 4.50m/s, has a head-on collision with a 0.090 kg ball initiallymoving in the same direction at a speed of 3.00m/s. Assuming a perfectly elastic collison, determine the speed anddirection of each ball after the collision?

Explanation / Answer

Applying the law of conservation of momentum we have, m1u1+m2u2=m1v1+m2v2 0.06*4.5+0.09*3=(0.06+0.09)v v=3.6m/s. Hence we get by it. "Hope this helps!Best of luck for the rest of yourcoursework."
