    70kg is sliding up on a hill side at an A mass m incline angle 0 = 30°. The initial velocity of the mass is vi 30m/s, and no external force is applied to the mass on the incline. The height of the structure ish = 25 m Note that the static friction coefficient of snow is i, = 0.5, and kinetic friction coefficient of snow is 0.4. Use the principles of energy and work to find the answen to...

    university physics please show your work ..sliding down a grass hill on a piece of cardboard was a fun summer activity! There was a hill near a park in south St. Louis that had an incline of something like 30 degrees. Once I got started on the top of the hill, I could ride for a distance on the order of 50 meters before arrived at the bottom of the hill. At that time, my mass was just a puny...

    1) Shayla is sliding in a sled from a top of a 5-m-high snow hill ( starting from rest.) At the bottom of the hill, her sled hits Tom, who falls into the sled. Toms's mass is the same as Shayla's and her sled altogether. What is the speed of the sled after Tom fell in? Neglect friction w/ snow. 2) You are standing by a smooth frozen lake, and longing to propel a snowball over the lake. In which...

    Now assume that the object is a solid sphere and instead of sliding down the hill, it ROLLS down the hill. It still starts from rest at a height of 1.4 m. Determine how fast it will be going at the bottom of the hill. Assume no thermal energy is generated and express your answer using appropriate mks units. Round your answer to the NEAREST THOUSANDTH

    Vo 5) h 200 m A driver coasts down a hill 200 m high with initial speed vo 40 m/s. The road has friction that results in a negative work -1.7 x 10 J. The effect of this is that the total initial energy is reduced by this amount by the time the car reaches the bottom of the hill. Calculate the speed of the car when it reaches the bottom of the hill. The mass of driver and passenger...
