Question

A 1500 kg car rounds a banked turn at the ideal speed so that no friction is necessary. The turn has a radius o curvature of 100 m and is sloped 25degree from horizontal. What is the strength of the normal force acting on the car from the road?. 6200 N 13300 N 14700 N 16200 N 34800 N Glass has a density of about 2500 kg/m^3. If a 2 kg block of glass is sitting on the bottom of a freshwater fish tank, what is the normal force on the floor of the tank? 2 N 8N 12 N 20 N 49 N A floating cube is 10 cm on a side and has a density of 400 kg/m^3. It is floating in fresh water that has a density of 1000 kg/m^3. What percentage of the cube is above the surface of the water? 0% 60% 20% 100% 40% A 40 N object is hung from a scale and dunked in water (density of 1000 kg/m^3), the measurement on the scale is only 30 N. What is the density of the object? 250 kg/m^3 750 kg/m^3 1000 kg/m^3 1333 kg/m^3 4000 kg/m^3.

Explanation / Answer

20) For banking on roadwithout driction,

Cosine component of normal balances weight and sine component provides cetripetal force.

N cos 25 degree = 1500*9.8

N = 1500*9.8/cos 25 degree

= 16200 N

hence (d) is correct
