Concept explainers
In an egg-dropping contest, a student encases an 85-g egg in a large Styrofoam block. If the force on the egg can’t exceed 28 N, and if the block hits the ground at 12 m/s, by how much must the Styrofoam compress on impact? Note: The acceleration associated with stopping the egg is so great that you can neglect gravity while the Styrofoam block is slowing due to contact with the ground.

- A desperate hiker has to think fast to help his friend who has fallen below him. Quickly, he ties a rope to a rock of mA = 405 kg and makes his way over the ledge (see the figure below). If the coefficient of static friction between the rock and the ground is H=0.348, and the mass of the hiker is ma= 70.1 kg, what is the maximum mass of the friend, mc, that the rock can hold so the hikers can then make their way up over the ledge? Assume the rope is parallel to the ground and the point where the rope passes over the ledge is frictionless. (ANS: 70.8 kg)arrow_forwardA person steps horizontally off the roof of a single-story house that is 3.1 m high. When his feet hit theground below, he bends his knees such that his torso decelerates over a distance of 0.65 m before coming to astop. If the mass of his torso is 50 kg, what is the average net force exerted on his torso over this distance?arrow_forwardA 80.0 kg mail bag hangs by a vertical rope 3.5 m long. A postal worker then displaces the bag to a position 2.4 m sideways from its original position, always keeping the rope taut.arrow_forward
- Training is over, and the zombie apocalypse is upon us. You are at the top of a 50-m-high hill. A zombie horde is amassing at the bottom of the hill. You release the brakes on a 4500-kg car parked at the top of the hill to send it driving in to the horde. If the zombies are packed in tight and provide a resistive ”frictional force” of 8 × 104 N, how far does the car make it through the horde before coming to a stop?arrow_forwardYou're standing at the top of a snow-covered hill, sloped at 20.0°. The coefficient of kinetic friction between your sled and the hill is 0.534. Unfortunately, there's a running stream just at the bottom of the hill, and you don't want to get wet. If you and your sled together have a mass of 87.0 kg, with what speed should you push off with to stop just before the stream, 77.0 m down the slope?arrow_forwardThe coefficient of friction between the wheels of Yamaha motorcycle and the dry pavement is 0.88. An animal walks out into the road, causing a motorcyclist to slam on the brakes. The wheels stop turning, but the tires skid along the road, causing intense friction and heat. Determine the magnitude (positive) of the acceleration which the 224-kg motorcycle experiences while skidding to a stop. The mass includes the rider. Answer: m/s/s (or m/s²)arrow_forward
- The coefficient of friction between the tires of Shirley's 1985 Ford Coupe and the dry pavement is 0.74. She doesn't drive the car often because it's becoming an antique, but she took it out for a gentle drive yesterday. While driving, she has to suddenly and forcefully brake when the light turned red. She probably shouldn't have been texting and driving! Her car (mass = 1.31x10³ kg) skids to a stop with an acceleration of m/s². Use the approximation g = 10 m/s².arrow_forwardThe coefficient of friction between the tires of Shirley's 1985 Ford Coupe and the dry pavement is 0.71. She doesn't drive the car often because it's becoming an antique, but she took it out for a gentle drive yesterday. While driving, she has to suddenly and forcefully brake when the light turned red. She probably shouldn't have been texting and driving! Her car (mass = 1.39x103 kg) skids to a stop with an acceleration magnitude of _____ m/s2. Use the approximation g ≈ 10 m/s2.arrow_forwardA driver in a 1000 kg car traveling at 36 m/s slams on the brakes and skids to a stop. If the coefficient of friction between the tires and the horizontal road is 0.80, how long will the skid marks be?arrow_forward
- A boy coasts down a hill on a sled, reaching a level surface at the bottom with a speed of 7.2 m/s. If the coefficient of friction between the sled's runners and snow is 0.040 and the boy and sled together weigh 490 N, how far does the sled travel on the level surface before coming to rest?arrow_forwardYou are driving through the Ouachita Mountains at 12m/s. You see a maple-leaf oak (Quercus acerifolia) crossing the road and hit the brakes, 20m away. The coefficient of kinetic friction between your tires and the road is μ_k = 0.7. Will you strike this endangered broadleaf? Justify your answer with a calculation.Your final answer should be the distance you will travel before coming to a stop.arrow_forwardA heavy crate is suspended from two ropes as it is lowered from a high shelf to the floor at a constant speed. One of the ropes makes an angle of 28.2 degrees with respect to the vertical and has a tension of 950 N, while the other makes an angle of 33.7 with respect to the vertical. What is the crate's mass in kg?arrow_forward
