Use the diagram below to answer the next 3 questions. An object starts from rest at a height of 5.00 rn, and then slides off a frictionless ramp. When it leaves the ramp, it is at a height of 3.00 m and it has a horizontal velocity vs. 11'- = NR 8 Find the horizontal velocity the at the end of the ramp. Your solution could involve the the law of conservation of energy, or you could use kinematics. The mass of the object is irrelevant, but if you feel you need it you could set it to 1.00 kg. NR 9 From the diagram, nd the time, t, it takes for the object to hit the groUnd, once it leaves the ramp. NR ll] Calculate the horizontal distance x, also known as the range. To allow EVERYONE [he chance lo get [his righl, you will assume thul the horizonlal velocily was 9.65 mfs A skier starts from rest at the top ofa luincline and skis in a straight line to the bottom of the slope, a distance d [measured along the slope] of 400 m. If the coefficient of kinetic friction u between the skis and the snow is 0.20. calculate the skier's speed at the bottom of the run. [4 marks] You do not need the skier's mass to solve this problem. lfyou feel you must have it, then make it be IIJO kg. There are TWO Ways to solve this: one involves the revised formula JFor conservation of energy that you learned in this unit. the other uses dynamics and kinematics. You can do it both ways. ofcom'se. I will give extra credit ifyou do [2 marks)
