- An 8 kg block is shot up an incline of 300with an initial speed of 3.6 m/s. How far up the incline will the block travel if the coefficient of friction between it and the incline is 0.22? Hint: Express the height above the ground that the block is above the incline in terms of the distance up the incline (hypotenuse).A 52 kg skier starts from rest at height H = 17 m above the end of a ski-jump ramp (see the figure). As the skier leaves the ramp, his velocity makes an angle of 0 = 25° with the horizontal. Neglect the effects of air resistance and assume the ramp is frictionless. (a) What is the maximum height h of his jump above the end of the ramp? (b) If he increased his weight by putting on a 10 kg backpack, what would h be? End of H ramp (a) Number i Units (b) Number i Units >Suppose I need to toss an object of mass 5.2 up onto a shelf 5.94 meters above where my hands can reach. What is the minimum speed of toss necessary to do this? Your answer should be in meters per second, but don't write teh unit, just the number. You can approximate the acceleration due to gravity at the earth's surface as 10 meters per square second.
- A block is given an initial velocity of 5.00 m/s up a frictionless incline of angle of 20.0°. How far up the incline does the block slide before coming to rest? Answer: 3.73 mA luggage handler pulls a 15 kg suitcase up a ramp inclined at an angle 33⁰ above the horizontal by a horizontal force F of magnitude 180 N. The coefficient of kinetic friction between the ramp and the suitcase is 0.35. If the suitcase travels 1.6 m along the ramp, calculate (e) If the package started from rest, what is its speed after it has travelled 1.6 m?A 4kg block was released from rest on top of a quarter circular surface. If the vertical height from A to B is given as 4m as shown below, If the surface A to B is frictionless, what is the coefficient of friction on surface B to C if the block slid through A to C until it totally stops at C due to friction?
- A box starts from rest and slides 40 m down a frictionless inclined plane. The total vertical displacement of the box is 20 m. How long does it take for the block to reach the end of the plane?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?John reached a speed of 29 m/s in the downhillskiing competition. Suppose he left the slope at that speed andthen slid freely along a horizontal surface. If the coefficient ofkinetic friction between his feet and the ground was 0.27 andhis final speed was half of his initial speed, find the distance hetraveled.
