Stop at the corner just before you enter the intersection. You don't need to pass the limit line because you are in a violation. Just stop at the corner of the back of the crosswalk and limit line. Even though there is no crosswalk you need to stop at the corner.

Answer:

The best answer to the question: If there is no crosswalk or limit line near an intersection, you should stop _____, would be, C: at the corner.

Explanation:

This regulation is part of what is taught to drivers before they get their drivers license. In essence, the regulation says that if you come to an intersection, and there is a limit line, or a crosswalk, of course you know you must stop before moving on. The problem comes when neither a crosswalk, nor a limit lines is marked near the intersection. To solve this, the regulation states that even if there are no such limiting lines, or marks, the driver must still come to a stop at the corner, before entering the intersection. This is why the anwer is C.

A 37 N block rests on a horizontal surface. The coefficients of static and kinetic friction between the surface and the block ar
Ne4ueva [31]

Answer:

The frictional force acting on the block is 14.8 N.

Explanation:

Given that,

Weight of block = 37 N

Coefficients of static = 0.8

Kinetic friction = 0.4

Tension = 24 N

We need to calculate the maximum friction force

Using formula of friction force

f=\mu mg

Put the value into the formula

f=0.8\times37

f=29.6\ N

So, the tension must exceeds 29.6 N for the block to move

We need to calculate the frictional force acting on the block

Using formula of frictional force

f = \mu N

Put the value in to the formula

f=0.4\times37

f=14.8\ N

Hence, The frictional force acting on the block is 14.8 N.

A block of ice is sliding down a ramp of slope 40 to the horizontal. What is the rate of acceleration of the block? Assume the f
uysha [10]

The given problem can be exemplified in the following diagram:

Since there is no friction or any other external force, the only force acting in the direction of the movement is the component of the weight of the block, therefore, applying Newton's second law:

\Sigma F=ma

Replacing the values:

mg\sin 40=ma

We may cancel out the mass:

g\sin 40=a

Using the gravity constant as 9.8 meters per square second:

9.8\frac{m}{s^2}\sin 40=a

Solving the operations:

6.3\frac{m}{s^2}=a

Therefore, the acceleration is 6.3 meters per square second.
