A 70kg car drives through a curve with radius 50m. What is the minimum angle the road should be tilted to keep the car on the ro
worty [1.4K]

when car moves along a circular path then centripetal force for taking turn will be provided by the component of normal force

Let the road is tilted by some angle

so force equations are given as

F_n cos\theta = mg

F_n sin\theta = \frac{mv^2}{R}

now divide two equations

tan\theta = \frac{v^2}{Rg}

now as it is given to us that

v = 80 km/h

v = 80* \frac{5}{18} = 22.2 m/s

R = 50 m

now we have

tan\theta = \frac{22.2^2}{50*9.8}

tan\theta = 1

\theta = tan^{-1}1

\theta = 45^0

so it is inclined at an angle of 45 degree

the near miss of toutatis. the 5-kilometer asteroid toutatis passed a mere 1.5 million kilometers of earth. calculate the probab
Lunna [17]

Answer:

Probability = 0.004247

This will not classify as a "Near Miss) since it is a very low probability

Explanation:

The solution for this question is based on the formula for probability.

Probability = \frac{e_{d} }{e_{t} }

Where

e_{d} = Desired outcome

e_{t} = Total outcomes

Since we know that the asteroid passed 1.5 million km of earth and the earth has a radius of is 6,371 km. We assume the asteroid has a trajectory that can only deviate in one direction (i.e. perpendicular to the earths surface) we input the following values into the formula

e_{d} = Desired outcome = 6,371 km

e_{t} = Total outcomes = 1,500,000 km

Probability = \frac{6,371 }{1,500,000}\\ Probability = 0.004247

Describe the relationship between the masses of two objects and the force of gravity between them.
professor190 [17]

Since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. So as the mass of either object increases, the force of gravitational attraction between them also increases.
