A spring gun (k = 25 N/m) is used to shoot a 56 g ball horizontally. Initially the spring is compressed by 16 cm. The ball loses contact with the spring and leaves the gun when the spring is still compressed by 12 cm. What is the speed of the ball when it hits the ground, 1.3 m below the spring gun?

If an autosome is present in only one copy at conception, that individual will not develop to term. Yet human males have only one copy of the X chromosome and they do develop normally. Why the difference? Discuss.

Lucy's ancient bones to tour US
The skeleton of the fossilised, 3.2 million-year-old human ancestor known as Lucy, will go on display in the US, Ethiopian officials say.
After four years of negotiations with the Houston Museum of Natural Science in Texas, Ethiopia agreed to lend the bones for scientific study until 2013. It is hoped Lucy's 11-leg tour will boost tourism and increase Ethiopia's profile as the "home of all humanity". She will leave her country of origin - and the origin of mankind - in June. As well as Lucy, the travelling exhibition will also include about 190 other Ethiopian artefacts including humankind's earliest stone tools. Officials say money from the tour will be used to improve museums across the country.
