if a certain car, going with speed v1, rounds a level curve with a radius r1, it is just on the verge of skidding. if its speed
schepotkina [342]

Answer:

The correct answer is 4R1

Explanation:

According to the given scenario ,the radius of the tightest curve on the same road without skidding is as follows:

As we know that

Centeripetal Acceleration is

= v^2 ÷ r

In the case when velocity becomes 2 times so the r would be 4 times

So, the radius of the  tightest curve on the same road without skidding is 4R1

What is the power generated by a 45 kg person who walks up a flight of 12 stairs, each 30 cm high, in 12 s?
Free_Kalibri [48]
The total distance covered by the person is 12 times the height of each stair:
\Delta h=12 \cdot 30 cm=360 cm=3.60 m

The work done by the person to climb the stairs is equal to the increase in his gravitational potential energy:
W= \Delta U=mg \Delta h=(45 kg)(9.81 m/s^2)(3.60 m)=1589.2 J

And therefore, the power generated by the person in 12 s is the work done divided by the time taken:
P= \frac{W}{t}= \frac{1589.2 J}{12 s}=132.3 W

So, the correct answer is B.

A baseball is thrown at an angle of 40.0° above
monitta
Vector trigonometry can be used for this problem. Since the horizontal component is 12 meters per second, this is technically the hypotenuse (actual initial velocity) multiplied to cosine of 40 degrees. Therefore, to find the hypotenuse, we must divide 12 by cosine 40degrees. cos(40)= 0.766, and 12/0.766 = approximately 15.664, therefore our answer is (3) 15.7 m/s
