Great! I've done (ii) and (iii) and managed to get the correct values. However, i can't seem to get the final one.

Oh! I get it now. It would be the same speed as the bird, correct? So, 7.39 m/s ?

Okay well I tried it in a new foruma: v2 = v02 + 2ay(y - y0) v2 = v02 + 2ay(y - y0) v2 = 0 + 2(-9.8)(0 - 4.69) v2 = 91.924 v = 9.59 m/s I come up with the same answer?

So how can I do the ones I got incorrect?

Homework Statement A sea bird catches a fish and then flies in an easterly direction with a speed v=7.39 m/s, h = 4.69 m above the surface of the sea. The fish has a mass of 115.3 g and is still alive. It thrashes and wiggles and as a result the bird drops the fish. i) What is the speed...

So I assume my working out and answers are correct?

Homework Statement A railway carriage with a mass m = 2.45×104 kg is initially traveling to the left with a speed Vi = 3.33 m/s. It collides and couples with (get stuck to) two identical railway carriages move to the left with a speed of Ui = 1.69 m/s. 1. What is the speed of the...
