Answer:

675J

Explanation:

Given parameters:

Force = 45N

Distance = 15m

Unknown:

Work done by Sheila = ?

Solution:

Work done by a body is the amount of force applied to make a body move through a distance;

Work done = Force x distance

Now;

Work done = 45 x 15 = 675J

What is the answer to this equation? M¹u¹ + M²u² = M¹V¹ + M¹V²

Rudik [331]

Answer:

m²=m¹

Explanation:

m¹v¹ + m²v² = m¹ v¹+m¹v²

m²v²= m¹v²

m²v²/v² = m¹

m² = m¹

The ball and socket joint in the hip is similar to the ball and socket joint of the shoulder but is designed more for __________

Viktor [21]

Answer:

a. power

b. precision

Explanation:

The hip is a spherical joint that allows the upper leg to move from front to back and from side to side. The largest joint that supports weight in the body, the hip joint is surrounded by strong ligaments and muscles.

It differs mainly with the circular articulation of the shoulder since it allows it to perform movement of greater power and with greater precision

Friction pulls directly against the direction of motion (at 180) of a sled, and does -55.2 J of work while the sled moves 8.98 m

zvonat [6]

The magnitude of the force of friction is 6.1 N

Explanation:

The work done by a force when moving an object is given by the equation:

$W=Fd cos \theta$

where :

F is the magnitude of the force

d is the displacement

$\theta$ is the angle between the direction of the force and of the displacement

In this problem, we have:

W = -55.2 J (work done by the force of friction)

d = 8.98 m (displacement of the sled)

$\theta=180^{\circ}$ (because the force of friction acts opposite to the direction of motion)

By solving the equation for F, we find the magnitude of the force of friction on the sled:

$F=\frac{W}{d cos \theta}=\frac{-55.2}{(8.98)(cos 180^{\circ})}=6.1 N$
