3. Two platforms 50m in height have pigs on them. The bird succeeds in impacting with both of these. S=ut + ½ at2 can be rearranged into the form: ½ at2 + ut – s =0 This is a quadratic equation. [ ax2 + bx +c =0 ] Use this to calculate: I. The times at which the bird impacts...

How do I put the information into a formula?

This is the only information that was given to me, I can't make sense of this question..

Homework Statement Two platforms 50m in height have targets on them. An object succeeds in impacting with both of these. S=ut + ½ at2 can be rearranged into the form: ½ at2 + ut – s =0 This is a quadratic equation. [ ax2 + bx +c =0 ] Use this to calculate: I. The times at which the...

The velocity at which ball A recoils after impacting with ball B -0.7698907956318254 The velocity at which ball B collides with ball C 2.7301092043681745 The velocity at which ball B recoils from ball C 0.9256192165494838 The velocity at which ball C is moving after ball B has...

Thanks, I'll try.. I've never done Physics before!

Mass; Ball A = 0.5 kg Ball B = 0.782 kg Ball C = 0.386 kg No friction just that ball A is moving at 3.5ms on a flat surface

Homework Statement The first ball (A), of mass 0.5 Kg is rolled towards the second (B) at a velocity of 3.5 ms. Ball B then impacts ball C. Assume this collision is perfectly elastic. Calculate: a. The velocity at which ball A recoils after impacting with ball B. b. The velocity...
