4 0

The acceleration of the truck, given it accelerated from 0 m/s to 22 m/s in 8.5 s is 2.59 m/s²

From the question given above, the following were obtained:

  • Initial velocity (u) = 0 m/s
  • Final velocity (v) = 22 m/s
  • Time (t) = 8.5 s
  • Acceleration (a) =?

<h3>How do I determine the acceleration?</h3>

The acceleration of the truck can be obtained as follow:

a = (v – u) / t

a = (22 – 0) / 8.5

a = 22 / 8.5

a = 2.59 m/s²

Thus, we can conclude that the acceleration of the truck is 2.59 m/s²

Describe the principle of conversation of energy:
exis [7]

Answer: Energy can neither be created nor destroyed, rather it is converted from one form to another

Explanation:

The principle of conversation of energy explains how energy is conserved in nature by being converted from one form to another such that no energy is created nor destroyed.

Practical examples include:

- electrical pressing iron that converts electrical energy to heat energy

- solar panels that converts solar energy to electrical energy

- Car batteries that converts chemical energy to light energy etc

A piece of driftwood moves up and down as water waves pass beneath it. However, it does not move toward the shore with the waves
pantera1 [17]

Answer:

It's A

Explanation:

As the waves progress through the medium, the particles they are made of move perpendicular to the direction in which the waves move. The particles do not move with the wave. So waves transmit energy but not matter as they progress through a medium.

dalvyx [7]

Explanation:

charles law V1/T1 =V2/T2

560 x 673 =V2/973

376880 = V2/973

V2 = 376880 x 973 = 366704240mL

Does air resistance affect the motion of a falling object differently when the mass is greater?
mixas84 [53]
<span>NO.

Air resistance does not affect the motion of a falling object differently when the mass is greater because the mass of an object does not in any way affect the speed of falling due to gravity, and air resistance depends only on the speed of the object and its surface area.</span>

If a force of 30N is applied to an object of mass 8kg which is kept on a surface, it achieves an acceleration of 3m/s. What is t
Eduardwww [97]

By Newton's second law, the net force on the object acting parallel to the surface is

∑ F = F[applied] - F[friction] = (8k g) (3 m/s²)

If F[applied] = 30 N, then

30 N - F[friction] = 24 N   ⇒   F[friction] = 6 N

so the answer is B.
