A 19.0 kg box is placed at the top of an inclined plane and released to either move freely or sit at rest. The plane is at an angle of 30° above the ground and has a total length of d = 2.80 m along the incline.

A woman at an airport is rolling her suitcase (mass = 20 kg) at an initial velocity of 1 m/s by pulling on a strap at an angle of 30° above the horizontal with a force of 33 N. The woman starts to speed up when she realizes that she is late for her flight. She pulls the suitcase over a distance of 50 m as she walks to her gate. What is the speed of the suitcase when she reaches her gate? (You can neglect friction in this problem. Give your answer in m/s.)
The designer of a ski resort wishes to have a portion of a beginner's slope on which the snowboarder's speed will remain fairly constant. Tests indicate the average coefficients of friction between a snowboard and snow to be u, = 0.105 and μ = 0.089. What should be the slope angle of the constant-speed section? Answer: 0= i
Under the influence of its drive force, a snowmobile is moving at a constant velocity along a horizontal patch of snow. When the drive force is shut off, the snowmobile coasts to a halt. The snowmobile and its rider have a mass of 143 kg. Under the influence of a drive force of 220 N, it is moving at a constant velocity whose magnitude is 4.38 m/s. The drive force is then shut off. Find (a) the distance in which the snowmobile coasts to a halt and (b) the time required to do so. (a) s= (b) t = i i + +
On the top of an 80 m tall building, there is a spring of 100 N/M were located 6.22 m away from the edge. Meanwhile, you are riding a crate which has negligible mass. You then compress the spring for about 0.87 m. Using your own mass, calculate how far you’ll go if the surface has a coefficient of kinetic friction of magnitude 0.3? Please answer correctly, comprehensively, and completely. As based on experience, some expert answers were wrong. Thank you.
