A student slides a 2,50 kg textbook across a table, and it comes to rest after travelling 1.15 m. The friction coefficient between the table and the book is 0.35. How much is the initial speed of the book?If wewanted the book to slide a distance of 3.50 m, how much should be the friction coefficient between the table and the book?
Lhte In 2012, Austrian skydiver, Felix Baumgartner, set a record for the highest exit altitude of 127 852 feet. He jumped from a helium balloon located in the Earth's stratosphere (see figure). At that altitude the atmosphere is too thin to breathe, so Baumgartner wore a special pressurized suit. During his free fall toward the earth, he reached a maximum speed of 843.6 mph, which is greater than the speed of sound. This set a record for greatest speed achieved during free fall and also set off a small sonic boom heard by his friends and family on the ground. Assume the effect of air resistance can be neglected and the acceleration due to gravity remains constant during his fall with a value of 9.807 m/s² and calculate the distance he fell before reaching 843.6 mph.

1. You are conducting an experiment to find the kinetic coefficienct of friction between a 5kg box and a ramp. The ramp has an angle of 25° above the horizontal. You start the box from rest. release it. and let it slide down the ramp. a) If the box starts at a height of 1 meter above the ground. what is the theo- retical value of its velocity at the bottom of the ramp? b) When you do the experiment, you find that the experimental value of the final velocity is 3.5 m/s. How much mechaical energy was “lost”? c) Assume that all of the mechanical energy 'lost' in part b) was due to Friction. Draw a free-body diagram. and determine the magnitude of the Normal Force acting on the box. d) Using the Normal force, determine the co-efficient of friction between the box and the ramp, if the system lost the amount of energy you caculated in part b). Hint: Use the work done by friction.
