Exciting Gravity and Friction Challenge with Olympic Skier Tina Maze!
How can we determine Tina Maze's acceleration as she skis down a steep slope?
What is Tina Maze's speed 3.6 seconds after starting?
Acceleration and Speed Challenge Accepted!
Part A: Tina Maze's acceleration is 8.24 m/s². The formula for finding acceleration is given by f_net = ma; Where f_net is the net force, which is equal to the difference between the gravitational force (mg) and the force of friction (f_friction). m is the mass of the skier. a is the acceleration, which we have to find. We can see that the gravitational force acting on the skier is given by: mg = mgsinθThe force of friction acting on the skier is given by: f_friction = μmgcosθ. Substitute the given values in the formula and find acceleration.
Part B: Tina Maze's speed 3.6 seconds after starting is 29.6 m/s. We can use the formula v = u + at; Where, u is the initial velocity = 0 as the skier starts from rest. t is the time = 3.6 s; a is the acceleration = 8.24 m/s². Calculate the speed of the skier 3.6 seconds after starting.
