Q1. While on vacation you rent a moped and go cruising around a tropical island. If you take a 10.0 degree banked curve with a radius of 15.0 meters at 12.0 m/s, what is the minimum coefficient of static friction between your tires and the road to keep the tires from slipping as you negotiate the curve?
Q2. A 10.0 g bullet is fired horizontally into a 104g wooden block that is initially at rest on a frictionless horizontal surface and connected to a spring having spring constant 157N/m. The bullet becomes embedded in the block. If the bullet-block system compresses the spring by a maximum of 70.0cm, what was the speed of the bullet at impact with block?
Now a peg is placed 4/5 of the way down pendulum's path so that when the mass falls to its vertical position it hits and wraps around the peg. As it wraps around the peg and attains its maximum height it ends a distance of 3/5 L below its starting po..
A diver 50 m deep in 10 degrees Celsius fresh water exhales a 1.2 cm diameter bubble. What is the bubble's diameter just as it reaches the surface of the lake, where the water temperature is 35 degrees Celsius? Suppose that the air bubble is always i..

If the weight of a room full of water is so great, why don't the first floors of houses built over basements all collapse as flooded to the ceiling.
A particular organ pipe can resonate at 213 Hz, 355 Hz, and 497 Hz, but not at any other frequencies in between. What is the fundamental frequency of pipe.
Suppose the speed of light in a vacuum were only 25.5 mi/h. Find the length of the bicycle being ridden at a speed of 20.0 mi/h as measured by an observer sitting on the park bench, given that its proper length is 1.59 m.
A heavy piece of hanging sculpture is suspended by a 146.0 cm long, 8.03 gm wire. When the wind blows hard, wire hums at its fundamental frequency of 113.0 Hz. What is the mass of the sculpture (in kg) assume that the local acceleration due to gravit..
A ferrari race car on the straight road starts from rest, accelerating at 2.00 m/s^2 until it reaches a speed of 20.0m/s. Then the car travels for 20.0 s at the constant speed until the brakes are applied, stopping the truck in a uniform manner in an..
Find tension in the back muscle and the compressional force
Speedboat A negotiates a curve whose radius is 115 m. Speedboat B negotiates a curve whose radius is 194 m. Each boat experiences the same centripetal acceleration. What is the ratio vA/vB of the speeds of boats.
A certain car is capable of accelerating at a rate of 0.52 m/s2. How long does it take for this car to go from a speed of 27 mi/h to the speed of 33mi/h.
A friend of yours is loudly singing a single note at 411 Hz while racing toward you at 25.5 m/s on a day when the speed of sound is 341 m/s.
