At t = 0 the components of a radio-controlled car's velocity are vx = 0.5 m/s and vy = 1.2 m/s. Find the components of the car's velocity at t = 4.1 s, given that the components of its average acceleration during this period are ax = 2 m/s2 and ay = -1 m/s2.

vx' = 8.7 m/s

vy' = - 2.9 m/s

Explanation:

The average acceleration during a time period is given by the formula:

a = (v' - v)/(t' - t)

where,

a = average acceleration

v' = Final Velocity

v = Initial Velocity

t' = Ending Time

t = Starting Time

Now, for x-component of velocity:

a = ax = 2 m/s²

v' = vx' = ?

v = vx = 0.5 m/s

t' = 4.1 s

t = 0 s

Therefore,

2 m/s² = (vx' - 0.5 m/s)/(4.1s - 0s)

(2 m/s²)(4.1 s) = vx' - 0.5 m/s

8.2 m/s + 0.5 m/s = vx'

vx' = 8.7 m/s

For y- component of velocity:

a = ay = -1 m/s²

v' = vy' = ?

v = vy = 1.2 m/s

t' = 4.1 s

t = 0 s

Therefore,

- 1 m/s² = (vy' - 1.2 m/s)/(4.1s - 0s)

(- 1 m/s²)(4.1 s) = vy' - 1.2 m/s

- 4.1 m/s + 1.2 m/s = vy'

vy' = - 2.9 m/s

the focus of lesson 1 is newton's first law of motion - sometimes referred to as the law of inertia. newton's first law of motion is often stated as. an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

they are non-matter

explanation:

they are non-matter. basically, any type of energy or any abstract concept is an example of something that does not matter. other examples include dreams, magnetism, radio, and hate
