a sledder weighing 30kg, starts from rest and goes over the following course. he starts on a hill 12m above the ground, goes down the hill to point b which is flat ground, he then goes up to point c which is atop another hill 6m high. he passes point d which is at the bottom of the 6m hill, and keeps sliding to e, which is an unstated horizontal distance from d. He comes to a stop at e. a) find his kinetic energy at b and c b) the distance from d to e assuming an average friction of 50N

A skier with a mass of 63.0 kg starts from rest and skis down an icy slope that has a length of 53.0 m at an angle of 32 degrees with respect to the horizontal. At the bottom of the slope, the path levels out and becomes horizontal, the snow becomes less icy, and the skier begins to slow down, coming to rest in a distance of 122m along the horizontal path. What is the speed of the skier at the bottom of the slope? What is the coefficient of kinetic friction between the skier and the horizontal surface?
Bart Jumps Springfield Gorge on his skateboard. Springfield Gorge us 50m wide, and Bart has constructed a 1.0 m Hugh ramp inclined at 30° to the horizontal. Air resistance is neglected. Homer had calculated that he can jump the gorge if the ramp is inclined to 45°, and he attains a speed of 20m/s. Will Homer make it? If not, how far short of the other side is he when he drops below the level of the ground?
A skier is at the top of a hill with height h. Starting from rest, the skier goes down to a flat area. On this flat area, there is a section of the slope with length D where the snow has melted (there is friction here). After passing the melted section, the skier goes up a smaller hill of height h2. At the top of this hill there is a drop off and the skier launches off of it with a horizontal speed. At what horizontal distance from the base of the jump does the skier land?
In the winter sport of bobsledding, athletes push their sled along a horizontal ice surface and then hop on the sled as it starts to careen down the steeply sloped track. In one event, the sled reaches a top speed of 9.2 m/s before starting down the initial part of the track, which is sloped downward at an angle of 6.0°. What is the sled’s speed after it has traveled the first 100 m?
A skiier is moving at a speed of 2.50 m/s when passing the starting line on a hill that initially has a 20.0° slope. After 32.0 m the hill becomes steeper with a slope of 30° for the next 32.0 m until the finish line which is at an elevation of 30.0 m below the starting point. Assuming there is no friction or air resistance, how fast is the skiier moving at the finish line?
A student launches a small rocket which starts from rest at ground level. At a height h=1.04km, the rocket reaches a speed of vf=391m/s. At that height, the rocket runs out of fuel, so there is no longer any thrust propelling it. After the rocket's engine turns off at a height of h=1.04km, it continues to move upward due to the velocity that it reached. What is the rocket's acceleration, in meters per squared second, during the period from engine shutoff until it returns to the ground? Ignore air resistance.
A rocket accelerates at 25m/s2 from rest on a frictionless inclined surface. The inclined ramp has a height of 70m and makes a 32 degrees angle above the ground. The rocket stops accelerating at the instant it leaves the incline. If air resistance is negligible, what is the horizontal distance 'R' from the end of the ramp to the point of impact (where it hits the ground)? a) Draw a diagram of this situation and be sure to include the distance 'R' b) Calculate the distance 'R' from the end of the ramp to the point of impact. 1.Draw the clear diagram 2. Give the indicating distance 'R' 3. Show your work 4. Find vertical and horizontal components of velocity when rocket leaves ramp 5. Find distance 'R'
A stunt driver wants to make his car jump over cars parked side by side below a ledge. With what minimum speed must he drive off the ledge to clear the cars? The vertical height of the ramp is 1.50 m above the cars and the horizontal distance he must clear is 22.0 m.
Chapter 06, Problem 85 Your answer is partially correct. Try again. A water slide is constructed so that swimmers, starting from rest at the top of the slide, leave the end of the slide traveling horizontally. As the drawing shows, one person hits the water 5.00 m from the end of the slide in a time of 0.454 s after leaving the slide. Ignore friction and air resistance, find the height H in the drawing. Water slide H. 5.00 m Number Units 8.404
A student launches a small rocket which starts from rest at ground level. At a height h=1.04km, the rocket reaches a speed of vf=391m/s. At that height, the rocket runs out of fuel, so there is no longer any thrust propelling it. Take the positive direction to be upward. After the rocket's engine turns off at a height of h=1.04kmℎ=1.04km, it continues to move upward due to the velocity that it reached. What is the rocket's acceleration, in meters per squared second, during the period from engine shutoff until it returns to the ground?

You stand on the edge of a very tall building with three rocks, which you are going to throw off the edge. You throw the first rock straight outwards, the second rock at an angle 60° above the horizontal, and the third rock 30° below the horizontal. If you throw all three rocks with the same initial speed, which will be moving the fastest when it hits the ground? The first rock The second rock. They will all have the same speed. The third rock
