Q1. A car of mass = 1300 travelling at 56.0 enters a banked turn covered with ice. The road is banked at an angle, and there is no friction between the road and car's tires. What is the radius of the turn if = 20.0 (assuming the car continues in uniform circular motion around the turn)?
Q2. A 150 lb student rides a ferris wheel that rotates at a constant rate. At the highest point, the seat exerts a normal force of magnitude 110 lb on the student. What will the magnitude of this normal force be at the lowest point?
You can turn the crank at a maximum rate of 3 turns per second, but hand crank is connected to the coil through a set of gears that makes the coil spin at a rate 6 times larger than the rate at which you turn the crank. What is the maximum emf you ca..
How long does it take for amplitude to drop to half its initial value . How long does it take for mechanical energy to drop to half its initial value.
A superhero flies 147 m from the top of a tall building at the angle of 33 degrees below the horizontal. What is the vertical component of the superhero's displacement.
A 2.62 kg mass attached to a light string rotates on the horizontal, frictionless table. The radius of the circle is 0.4207 m, and string can support a mass of 14.70 kg before breaking.
A 59.0 kg pole vaulter running at 9.5 m/s vaults over the bar. If the vaulter's horizontal component of velocity over the bar is 1.5 m/s and air resistance is disregarded, how high was the jump.

A 77 person stands on the uniform ladder 4.0 long, that weighs 100. The floor is rough; hence, it exerts both a normal force, and a frictional force, on the ladder. The wall, on the other hand, is frictionless; it exerts only the normal force.
A gymnast of mass 56.0 {rm kg} hangs from a vertical rope attached to the ceiling. You can ignore the weight of the rope and assume that the rope does not stretch. Use the value 9.81 {rm m/s^2} for the acceleration of gravity.
