A typical jar that has been tightened to a reasonable degree requires 2.0 N⋅mN⋅m to open. f you grab a 8.2-cmcm-diameter jar lid with one hand so that your thumb and fingers exert equal magnitude forces on opposite sides of the lid, as in the figure, what is the magnitude of each of the forces?
Biologists have studied the running ability of the northern quoll, a marsupial indigenous to Australia. In one set of experiments, they studied the maximum speed that quolls could run around a curved path without slipping. One quoll was running at 2.8 m/s around a curve with a radius of 1.2 m when it started to slip. What was the coefficient of static friction between the quoll’s feet and the ground in this trial?
A) A merry-go-round at a children's park begins at rest and is pushed by a parent while a child holds onto the ride at the outer edge, 3.10 m from the center. The parent pushes with a constant force for 2.74 s until the child is moving with a speed of 11.0 m/s. What is the magnitude of the net acceleration on the child the instant before the parent stops pushing the merry-go-round? (Give your answer to at least one decimal place.)

- An amusement park ride called the Rotor debuted in 1955 in Germany. Passengers stand in the cylindrical drum of the Rotor as it rotates around its axis. Once the Rotor reaches its operating speed, the floor drops but the riders remain pinned against the wall of the cylinder. Suppose the cylinder makes 24.5 rev/min and has a radius of 3.70 m. What is the minimum coefficient of static friction ?sμs between the wall of the cylinder and the backs of the riders?arrow_forwardA 3500 kg flatbed truck is carrying an unsecured 400 kg box of wine glasses. The coefficient of static friction between the box and the truck bed is Usb=0.50, the coefficient of rolling friction between the truck's tires and the road is Urt=0.03. The truck comes to an unbanked curve in the road having a 40m radius. What is the maximum speed with which the truck can take the curve without damaging the wine glasses? Note that in order for the wine glasses to not be damaged, the box they're in should not slide on the truck bed and the truck itself should not slide on the road while taking the curve.arrow_forwardIf your speedometer reading is 45 mph, but your tires are larger than factory-installed tires, how fast is your SUV actually moving?
