5. (10 pts): A car of mass M goes around an icy banked turn of radius t at a speed v. If there is no frictional force and the car takes the turn without skidding, at what angle 0 is the turn banked?
In short-track speed skating, the track has straight sections
and semicircles 16 m
in diameter. Assume that a 64kg
skater goes around the turn at a constant 11m/s
.

2. In short track speed racing, the track has straight sections and semicircles on each end with radius 18 m. Assume a 61 kg skater goes around the turn at 11.3 m/s. a. What is the net horizontal force on the skater? Please draw a force diagram. b. What is the coefficient of friction necessary to just negotiate this turn?
A 1750kg indy car with a speed of 34m/s goes around a level, circular track with a radius 1.5km what is the centripetal acceleration of the car? what is the centripetal force of the indy car?
3. A frictionless roller-coaster goes around a circular loop of radius 11 m. It enters the bottom of the loop going 32 m/s. Find the speed of the roller-coaster when it gets to the top of the loop 4. For the loop in the previous problem find the velocity of the roller-coaster as a function of height off the ground. Use that to find the centripetal acceleration as a function of height. Plot the centripetal acceleration as a function of...
A car travels at a constant speed around a circular track whose radius is 2.65 km. The car goes once around the track in 341 s. What is the magnitude of the centripetal acceleration of the car?
