Question 10 (1 point)
When the student releases the water balloon, it swings forward. When the water balloon swings back, you can tell that the student expects the
water balloon to hit her face. Why does the water balloon not continue on and hit the student's face?

Answer:

9.8 m/s/s

Explanation:

The horizontal velocity of a projectile is constant (a never changing in value), There is a vertical acceleration caused by gravity; its valueis 9.8 m/s/s, down, The vertical velocity of a projectile changes by 9.8 m/s each second, Thehorizontal motion of a projectile is independent of its vertical motion.

Answer:

the horizontal component of the velocity, however, retains its initial value v0x=+115 m/s throughout the entire descent.

Explanation:

since the plane also travels at a constant horizontal velocity of +115 m/s, it remains directly above the falling package.

Answer:

it was given the name Newton (N). from this, the derived unit of energy (or work) is defined ,as the work produced when the unit of force causes a displacement equal to the unit of length of its point of application along its direction . It was given the name Joule (J).

Explanation:

Answer:

Consensus: the extent to which other people behave in the same way in a similar situation.

Consistency: refers to the way in which minority influence is more likely to occur if the minority members share the same belief and retain it over time.

Distinctiveness: refers to the extent to which a specific action engaged in by an individual is unusual or uncommon for that particular individual

Explanation:

Average velocity indicates direction and can be represented as a negative number when the displacement is in the negative direction. Average speed does not indicate direction and can only be positive or zero.

Answer:

D. The skier's weight, the force of friction between the skis and snow,

and the force of air resistance

Explanation:

If two objects, such as the the skier, and skies undergo a fast velocity downward, the net force is the total force or newtons which are all components of weight as apparent to mass and gravity, friction, which is the contact force of the skis on the snow, and air resistance which limits the air resistance is the opposite force acting on the object I'm the air relative to the density of air, cross sectional area of the object, the coefficient of drag which is based on the density of the object, it's area, and dynamic air pressure.

Answer:

As the ball falls from C to E, potential energy is converted to kinetic energy. The velocity of the ball increases as it falls, which means that the ball attains its greatest velocity, and thus its greatest kinetic energy, at E. 19.

Answer:

15.3 N

Explanation:

Force = mass x acceleration

= 2.55 kg x 6.00 m/s^2

= 15.3 kgm/s^2 = 15.3 N

The required force to accelerate a 2.55 kg remote-controlled toy car at a rate of 6.00 m/s^2 be 15.3 N.

The definition of force in physics is: The push or pull on a mass-containing item changes its velocity.

An external force is an agent that has the power to alter the resting or moving condition of a body. It has a direction and a magnitude. The application of force is the location at which force is applied, and the direction in which the force is applied is known as the direction of the force.

Given parameters:

Mass of the remote-controlled toy car : m = 2.55 kg.

Acceleration of  the remote-controlled toy car :a =  6.00 m/s^2

Now according to Newton's 2nd law of motion,

Force = mass x acceleration

= 2.55 kg x 6.00 m/s^2

= 15.3 kgm/s^2

= 15.3 N

Hence, required force is 15.3 N.

3. Newton’s third law explains how every action has an equal but opposite reaction, meaning that forces comes in pairs. While the locomotive’s wheels are pushing back against the ground as the action force, the ground is producing a reaction force towards the locomotive, propelling it forward. Another pair of forces that act on the locomotive is gravity and normal force. While gravity is pulling the locomotive towards the ground, the normal force the ground exerts on the locomotive is why the locomotive doesn’t fall through the ground.

4. The force of Earth’s gravity on the Sun is weaker than the force of the Sun’s gravity on Earth. The Sun’s attraction  affects the motion of Earth more than the Earth’s attraction affects the Sun’s motion because according to  Newton’s second law, force has mass as one of its factors. The Sun has a significantly higher mass than Earth,  meaning that its force of gravity would also be significantly higher. Newton’s third law is why the Earth doesn’t get  marginally closer to the Sun, stating that every action has an equal and opposite reaction. As the Sun is pulling  Earth towards itself, Earth is pulling away from the Sun.

Answer:

[tex]\boxed {\boxed {\sf 2 \ m/s^2}}[/tex]

Explanation:

Acceleration can be found by dividing the change in velocity by the time.

[tex]a=\frac{\Delta v}{t}[/tex]

The time is 1.25 seconds.  The change in velocity is the difference between the initial velocity and the final velocity.

[tex]\Delta v= 2.5 \ m/s\\t=1.25 \ s[/tex]

Substitute the values into the formula.

[tex]a=\frac{2.5 \ m/s}{1.25 \ s}[/tex]

Divide.

[tex]a=2 \ m/s^2[/tex]

The sprinter's average acceleration is 2 meters per second squared.

Answer: 2 m/s^2
