Finding acceleration= final speed-initial speed/time taken (or A=V-U\T)

Finial speed= 27.8s
Initial speed= 0s
Time taken= 5.15

So..

27.8-0/5.15= 5.40m/s (rounded to two decimal places)

Represent 7468 N with SI units having an appropriate prefix. Express your answer to four significant figures and include the app
sergeinik [125]

Answer:

7.468 kN

Explanation:

Here the force of 7468 Newton is given.

Some of the prefixes of the SI units are

kilo = 10³

Mega = 10⁶

Giga = 10⁹

The number is 7468.0

Here, the only solution where the number of significant figures is kilo

1 kilonewton = 1000 Newton

1\ Newton=\frac{1}{1000}\ kilonewton

\\\Rightarrow 7468\ Newton=\frac{7468}{1000}\ kilonewton\\ =7.468\ kilonewton

So 7468 N = 7.468 kN

What expression (formula) relates Kenetic energy of an object of mass to its momentum
zmey [24]

Answer:

Correct answer:  Ek = I² / 2 · m

Explanation:

The formula by which kinetic energy is calculated is:

Ek = m V² / 2

The formula by which momentum i prefer the name impulse is calculated is:

I = m V

We will transform the formula for kinetic energy on the next way:

Ek = m V² / 2  we will multiply numerator and denominator with m and get:

Ek = m² V² / 2 m = (m v)² / 2 m = I² / 2 m

Ek = I² / 2 m

God is with you!!!

A 0.56 kg model rocket produces 53 newtons of upward thrust as it shoots upward off the launch pad. With what acceleration meter
Yanka [14]

resultant force = thrust – weight

acceleration = resultant force (newtons, N) divided by mass (kilograms, kg).

Acceleration = resultant force divided by mass

53N/0.56

=94.64 approximately 95

= 95m/s^2

This means that, every second, the speed of the rocket increases by 95m/s2

the S.I unit of Acceleration is meter per second square.
