g If a car takes a banked curve at less than the ideal speed, friction is needed to keep it from sliding toward the inside of th

e curve (a real problem on icy mountain roads). (a) Calculate the ideal speed in (m/s) to take a 110 m radius curve banked at 15°.

Answer:

Speed; v = 17 m/s

Explanation:

We are given;

Radius; r = 110m

Angle; θ = 15°

Now, we know that in circular motion,

v² = rg•tanθ

Thus,

v = √(rg•tanθ)

Where,

v is velocity

r is radius

g is acceleration due to gravity

θ is the angle

Thus,

v = √(rg•tanθ) = √(110 x 9.8•tan15)

v = √(288.85)

v = 17 m/s

Two objects, A and B, are 10 m apart. Objects C and D are 20 m apart. The gravitational attraction between objects C and D is gr
sveticcg [70]

Answer:

F=\frac{Gm_1m_2}{r^2}

where , F = Gravitational force

G = Gravitational constant

m_1 = mass of first object

m_2 = mass of second object

r = distance between the two objects

As Gravitational force is inversely related to the distance between two objects, lesser is the distance , more will be the gravitational force. As distance between C and D is more , the force shoulld have been less. That means the product of the masses of the objects C and D is more than the product of the masses of the objects A and B.
