Pam (60 kg) starts sliding doun a 50-meter-high hill with her snowboard (10 points). a) Find...
A snowboarder starts from rest on an inclined planar snow surface and gives herself a tiny push to start sliding down the hill. The coefficient of kinetic friction between her snowboard and the snow is 0.08. She notices that she travels 26.53 m horizontally and 34.51 m vertically (downward) before whizzing by a marker flag.

1) Shayla is sliding in a sled from a top of a 5-m-high snow hill ( starting from rest.) At the bottom of the hill, her sled hits Tom, who falls into the sled. Toms's mass is the same as Shayla's and her sled altogether. What is the speed of the sled after Tom fell in? Neglect friction w/ snow. 2) You are standing by a smooth frozen lake, and longing to propel a snowball over the lake. In which...
