Question

A playdoh ball and a Frisbee both have a mass of 0.124 kg. The playdoh ball is moving

2.00 m/s when it collides with the stationary target Frisbee. Explain what happens next.

(This needs to include a numerical answer.)

Answer 1

Let m₁ = mass of the ball & m₂ = mass of the frisbee

Let v₁ = Initial velocity the ball before impact & v₂ = Initial velocity of the frisbee before impact

Let v₃ = velocity of both after impact. It is assumed that the 2 objects collide and stick together after impact

(No other problem information was given otherwise!)

Then m₁v₁ + m₂v₂ = (m₁ + m₂)v₃ inserting the information given

(.124kg)(2m/s) + (.124kg)(0m/s) = (.124 + .124)v₃

.248 = .248v₃

so, v₃ = 1 m/s
