xz_007 [3.2K]

Explanation:

Frictional force is need for walking and to allow motion. Without friction, walking and motion wouldn't be possible.

Frictional force is a force that opposes the direction of the motion of a body.

It is force that opposes motions and it is directed towards the opposite side of motion.

Without the force of friction within our feet and the ground, we will continue to slide indefinitely and not be able to have grip of our motion.

Friction restricts and helps to control motion.

Boy pulls a 5.0-kg sled with a rope that makes a 60.0° angle with respect to the horizontal surface of a frozen pond. The boy pu
kykrilka [37]

Answer:

0.1

Explanation:

mass, m = 5 kg

θ = 60°

Force, F = 10 N

velocity is constant , it means the net force is zero.

So, the component of force along the surface is equal to the friction force

FCosθ = friction force

10 x cos 60 = μ x m x g

where, μ is the coefficient of friction

5 = μ x 5 x 9.8

μ = 0.1

Thus, the coefficient of friction is 0.1

Jupiter, the largest planet in the solar system, has an equatorial radius of about 7.1 x 104 km (more than 10 times that of Eart
Oksi-84 [34.3K]
The average speed of an equatorial point is given by the ratio between the distance covered during one complete rotation (therefore, the circumference of Jupiter at the equator) and the time to complete one rotation:
v= \frac{S}{t}
where S is the circumference and t the time.

The radius of Jupiter is
r=7.1 \cdot 10^4 km = 7.1 \cdot 10^7 m
so the circumference at the equator is:
p=2 \pi r = 2 \pi (7.1 \cdot 10^7 m)=4.46 \cdot 10^8 m

While the time to complete one rotation is (in seconds)
t=9h 50 min=590 min = 35400 s

Therefore the average speed of a point at the equator is
v= \frac{4.46 \cdot 10^8 m}{35400 s}=1.26 \cdot 10^4 m/s
