29. What is the average velocity of an object that moves

Physics
1 answer:
Murljashka [212]3 years ago
3 0

Answer:

Average Velocity = - 1.22 cm/s = - 0.0122 m/s

Explanation:

The average velocity of an object is defined as the ratio of the total distance traveled by the object to the total time taken by the object to cover the distance. Therefore, the average velocity of an object can be found by the following formula:

Average Velocity = Total Distance Covered/Total Time Taken

Average Velocity = (Final Position - Initial Position)/Total Time Taken

Average Velocity = (3.7 cm - 6.5 cm)/(2.3 s)

Average Velocity = (- 2.8 cm)/(2.3 s)

<u>Average Velocity = - 1.22 cm/s = - 0.0122 m/s</u>

here, the negative sign indicates the direction of the velocity or the movement of the object is leftwards or towards the origin approaching from right.

Suppose that the space shuttle Columbia accelerates at 14.0 m/s2 for 8.50 minutes after takeoff.
givi [52]

Answer:

A. speed = 7.14 Km/s

B. distance = 1820.7 Km

Explanation:

Given that: a = 14.0 m/s^{2}, t = 8.50 minutes.

But,

t = 8.50 = 8.50 x 60

  = 510 seconds

A. By applying the first equation of motion, the speed of the shuttle at the end of 8.50 minutes can be determined by;

v = u + at

where: v is the final velocity, u is the initial velocity, a is the acceleration and t is the time.

u = 0

So that,

v = 14 x 510

 = 7140 m/s

The speed of the shuttle at the end of 8.50 minute is 7.14 Km/s.

B. the distance traveled can be determined by applying second equation of motion.

s = ut + \frac{1}{2}at^{2}

where: s is the distance, u is the initial velocity, a is the acceleration and t is the time.

u = 0

s = \frac{1}{2}at^{2}

  = \frac{1}{2} x 14 x (510)^{2}

 = 7 x 260100

 = 1820700 m

The distance that the shuttle has traveled during the given time is  1820.7 Km.

The coefficient of kinetic friction between an object and the surface upon which it is sliding is 0. 10. The mass of the object
lilavasa [31]

The force of friction is 78.4 N

What is force of friction?

Frictional force is the force created when two surfaces come into contact and slide against each other. it is given by the equation:

F_{f} = μ * F_{n}

where,

F_{f} = force of friction

μ = coefficient of friction

F_{n} = normal force

Given,

μ = 0.10,  m = 8.0 kg

We know,

F_{n} = mg

F_{n} = 8.0 * 9.8\\\\ F_{n} = 78.4 N

Subsituing the values in equation:

F_{f} = μ * F_{n}

F_{f} = 0.10 * 78.4 \\\\F_{f} = 7.84 N

The force of friction is 78.4 N.
