Physics help 1) A worker stands still on a roof sloped at an angle of 25° above the horizontal. He is prevented from slipping by a static frictional force of 450 N. Find the mass of the worker. 2) A stuntman is being pulled along a rough road at a constant velocity by a cable attached to a moving truck. The cable is parallel to the ground. The mass of the stuntman is 105 kg, and the coefficient of kinetic...
A 75 kg snowboarder slides down a hill that has a vertical drop of 6.0 m and is inclined at 31owith respect to the horizontal. The initial speed of the snowboarder at the top of the hill is 5.0 m/s. The coefficient of kinetic friction between the ramp and the snowboard is 0.20. A) Calculate the acceleration of the snowboarder The acceleration is 3.40 m/s B) Calculate the total work done on the snowboarder C) Using the work-energy theorem, calculate...
A Toboggan loaded with students (total weight 150N) slides down a snow covered slope. The at constant angle 45, and the toboggan is so well waxed that there is hill slopes a virtually no friction, What is its acceleration?
B4. A child in a sledge slides down a snow covered hill that is angled 45° below the horizontal. The coefficient of friction between the sledge and the snow is μ : 1/V3. At time t .. the speed of the sledge is u m/s. (a) What is the acceleration of the sledge parallel to the hill? (b) Derive an expression for the distance the sledge has travelled down the hill at time t 0. (c) At time t 0,...
Problem 11.56 A 4.5 kg box slides down a 4.3-m -high frictionless hill, starting from rest, across a 1.7-m -wide horizontal surface, then hits a horizontal spring with spring constant 550 N/m The other end of the spring is anchored against a wall. The ground under the spring is frictionless, but the 1.7-m-long horizontal surface is rough. The coefficient of kinetic friction of the box on this surface is 0.27. How far is the spring compressed? Express your answer to...
Before starting this problem consult Interactive Solution 3.73. A golfer, standing on a fairway, hits a shot to a green that is elevated 4.52 m above the point where she is standing. If the ball leaves her club with a velocity of 45.2 m/s at an angle of 41.6 ° above the ground, find the time that the ball is in the air before it hits the green.
A 5.0 kg box slides down a 5.0-m-high frictionless hill, starting from rest, across a 2.0-m-wide horizontal surface, then hits a horizontal spring with spring constant 500 N/m. The other end of the spring is anchored against a wall. The ground under the spring is frictionless, but the 2.0-m-wide horizontal surface is rough. The coefficient of kinetic friction of the box on this surface is 0.25. (a) What is the speed of the box just before reaching the rough surface?...
A 56-kg mother and her 32-kg son are sledding down a 20° incline when their 8-kg toboggan hits a small bump and the son falls off the sled (he was not holding onto the toboggan as instructed by his mother). After one second, the mother jumps off the toboggan to see if her son is unharmed. The son leaves the toboggan with zero relative velocity, and the mother has a relative velocity of 1 m/s up the hill when she...
Now we are going to look at the problem of an object sliding down a frictionless inclined plane. Suppose a toboggan loaded with vacationing students (total weight w) slides down a long, snow-covered slope. The hill slopes at a constant angle α, and the toboggan is so well waxed that there is virtually no friction. Find the toboggan’s acceleration and the magnitude n of the normal force the hill exerts on the toboggan. At what angle does the hill slope...
