Answer:

1) The person ma tend to fall

2) The person will remain upright

Explanation:

1) According to Newton's first law of motion, an object will continue in its state of rest or maintain its uniform motion on a straight line unless acted on by a force

Therefore, when a person steps off onto the floor from a walkway moving at 3 m/s, the friction between the floor and the person's feet prevents the forward motion of the feet, however the person's upper body will tend to continue with the forward motion, and the person may tend to tilt and fall over

2) If the person steps onto another walkway moving with the same velocity, the initial velocity of all parts of the person's body is maintained, such that the person will continue in his uniform motion without experiencing any force and therefore, the person will remain upright

A 185 g block is pressed against a spring of force constant 1.60 kN/m until the block compresses the spring 10.0 cm. The spring
denis-greek [22]

Answer:

d = 5.10 m

Explanation:

As we know that here on the plane of the inclined there is no frictional force

So in these cases we can say that total mechanical energy will always remains conserved

so here we can say that

spring potential energy = gravitational potential energy of the block

as we know from the formula

\frac{1}{2}kx^2 = mgh

now plug in the values in it

\frac{1}{2}(1.60 \times 10^3)(0.10)^2 = (0.185)(9.81)h

8 = 1.81 h

h = 4.42 m

now as we know that the angle of inclination is 60 degree and height raised is 4.42 m

so here maximum distance moved along the inclined plane will be

\frac{h}{d} = sin60

d = \frac{h}{sin60}

d = \frac{4.42}{sin60} = 5.10 m

Two charged objects have a repulsive force of .80 N. If the charge of one of the objects is doubled, then what is the new force?
sveticcg [70]
The new force would be 1.6 N.
Since the charges multiply as variables (q1)x(q2), then it would simply be double (q1)x(q2), or 1.6.
