Answer:

80m/s

Explanation:

to find it you have to work it out by using the formula distance divided by speed to find time.

The time taken by the skateboarder to reach the bottom 120m away is 80 sec.

Acceleration may be defined as the rate of change of the velocity of an object with respect to time. Accelerations are vector quantities as it has both magnitude and direction.

When an object moves in a circular path at a constant speed, it is still accelerating, because the direction of its velocity is changing. If an object is speeding up and moving in a positive direction, it has a positive acceleration.

According to the question,

Speed of the skateboarder = 1.5 m/s

The total distance needs to be traveled = 120m

Total time taken =?

The Formula for calculating time is as follows:

Therefore, the time taken by the skateboarder to reach the bottom 120m away is 80 sec.

Explanation:

Given that,

Mass of a skier, m = 55 kg

The vertical distance between start and finish is 10 m.

(a) The potential energy of a skier is given by :

[tex]E=mgh\\\\E=55\times 9.8\times 10\\\\=5390\ J[/tex]

(b) When she reaches the bottom of the hill, the potential energy is converted to kinetic energy. So,

[tex]5390=\dfrac{1}{2}mv^2\\\\v=\sqrt{\dfrac{2\times 5390}{55}} \\\\v=14\ m/s[/tex]

Hence, her potential energy is 5390 J and at the bottom of the hill she is moving with a speed of 14 m/s.

Answer:

Your answer should be B. a parabola.

Explanation:

The path of the projectile in the absence of friction is a parabola. Therefore, option (b) is correct.

Projectile motion can be described as a form of motion experienced by a projectile that is projected near the surface of the earth and moves along a curved path under the action of gravity. This curved path is to be a parabola, but may also be a straight line in special cases when the projectile is thrown directly upwards.

The study of such motions is known as ballistics and the only force that is actively exerted is gravity, which acts downward, thus giving the object a downward acceleration toward the Earth’s center of mass.

No external force is required to maintain the horizontal velocity component of the object's motion because of the object's inertia. Other forces, such as aerodynamic drag or internal propulsion need additional analysis.

Therefore, the path of an object or projectile is generally parabola in the absence of friction.

The horizontal velocity : vox = 1.33 m/s

Given

time 0.75 s

distance = 1 m

Required

the horizontal velocity

Solution

vox = horizontal velocity

x = distance

Can be formulated :

x = vox . t

Input the value :

1 m = vox . 0.75s

vox = 1 : 0.75

vox = 1.33 m/s

Answer: Core muscles protect the spine and keeps it stabilized. Also they can help control movements such as walking and standing. The core helps transfer energy and help us move in different directions. It's important to have a strong set of core muscles.

Explanation:

Answer:

The core muscles stabilize and protect the spine. They help control all movements and make it possible for us humans to walk and stand up right. The core helps us transfer energy, shift our body weight and reach/move in different directions. It is important to have a strong set of core muscles because it makes everyday activities easier.

Answer:

true..........................

Speed and velocity use the same formula for calculations. However, an object can have a different average speed and average velocity because of displacement. This is true statement.

As a vector quantity with both magnitude and direction, velocity has both. This term refers to the speed at which an object is moving or shifting positions.

Since speed is a scalar quantity, it lacks direction. It indicates the rate of a moving thing. When a particle's speed is high, it indicates that it is travelling quickly, and when it is low, it indicates that it is going slowly.

The displacement of a body during a period of time divided by the passage of time yields the average velocity of the body during that period.

The distance travelled by a body in a given amount of time, divided by the amount of time, is the body's average speed.
