You and your friends are doing physics experiments on a frozen pond that serves as a frictionless, horizontal surface. Sam, with mass 76.0 kg , is given a push and slides eastward. Abigail, with mass 56.0 kg , is sent sliding northward. They collide, and after the collision Sam is moving at 36.0 ∘ north of east with a speed of 6.20 m/s and Abigail is moving at 21.0 ∘ south of east with a speed of 9.20 m/s .

A) What was the speed of each person before the collision?
Sam's speed:

Abigail's speed:

B) By how much did the total kinetic energy of the two people decrease during the collision?

Proposition. You and your friends are learning to play hockey, and you decide to use physics to get better by analyzing your movements. You are skating directly towards your friend at (5.98, 0) M/S who is also skating directly towards you to get the puck at a constant velocity of (-2.7, 0) M/S, and both of you reach the puck at the same time, so you collide and stick together. At the same time your hockey helmet with a mass...

A 712 N student stands in the middle of a frozen pond having a radius of 5.9 m. He is unable to get to the other side because of a lack of friction between his shoes and the ice. To overcome this difficulty, he throws his 2.2 kg physics textbook horizontally towards the north shore at a speed of 6.0 m/s. How long does it take him to reach the south shore?

You have constructed a 5-kg toy iceboat which you set on a frictionless frozen pond when a sudden wind exerts a constant force on the boat of 100 N due west. Due to how you have set the sails, the wind causes the boat to slide 10.0 m in a straight line at 30◦ north of west. What is the speed of the boat at the end of those 10.0 m?

A hockey player is standing on his skates on a frozen pond when an opposing player, moving with a uniform speed of 5.0 m/s, skates by with the puck. After 1.50 s, the first player makes up his mind to chase his opponent. If he accelerates uniformly at 0.31 m/s2, determine each of the following. (a) How long does it take him to catch his opponent? (Assume the player with the puck remains in motion at constant speed.) (b) How...

You have some friends who are doing a group project with you. The goal is to test H0 : u = 5 vs H1 : u > 5. They have to go, but before they leave they tell you what they have found. They have a sample mean = 4.8, a critical number x bar ( this would be x with a bar over it ) critical = 4.9, ( xc = 4.9 , where the underline should be on...

Comment on the results of each of these recent experiments in light of the Old Friends hypothesis: a) A small group of Finnish children were matched at birth by age and relevant genotype, then followed to see if any developed autoantibodies typical of type I diabetes. Compared to matched healthy controls, the children who would develop T1D had markedly different gut microbiomes. Relative to those of matched healthy controls, rheir microbiomes were less diverse, more unstable, and became increasingly dominated...

You’re doing an experiment in a physics lab using ice and water. Do you have 1.5 kg water with temperature 28°C. You added 0.6 kg ice with initial temperature -22°C. Assuming you have an isolated system, i) write down the thermal equilibrium equations with amount of heat loss and gain in the system ii) do all the icemelt justify your answer with calculations iii) what is the final temperature of the water in the container and why? iv) if some...

(1)(A) Young's double slit experiment is one of the quintessential experiments in physics. The availability of low cost lasers in recent years allows us to perform the double slit experiment rather easily in class. Your professor shines a green laser (566 nm) on a double slit with a separation of 0.106 mm. The diffraction pattern shines on the classroom wall 4.0 m away. Calculate the fringe separation between the fourth order and central fringe. (B)Working in lab class you shine...
