SI Units are based on meters, kilograms, seconds, amperes, kelvins, candelas, and moles, together with a set of prefixes to indicate multiplication or division by a power of ten.
There are seven SI base units, which are:
m - Meter - Length.
s - Second - Time.
mol/Mole - Amount of Substance.
A - Ampere - Electric Current.
K - Kelvin - Temperature.
cd - Candela - Luminous Intensity.
kg - Kilogram - Mass.
I think that the delivered units are how they are used such as watts which are equal to one joule per second. Others are “ergs per second (erg/s), horsepower (hp), metric horsepower (Pferdestärke (PS) or cheval vapeur (CV)), and foot-pounds per minute.”
So, SI base units are the basic units of things such as length or temperature. This would mean that the delivered units are the specific units per something like miles per hour.
To write it in the form ai + bj, we need to find a and b
which are:
a = x component
b = y component
length of x = 9 – 2 = 7
length of y = 25 – 1 = 24
tan θ = 24 / 7
θ = 73.74°
a = (50 m/s) cos 73.74
a = 14 m/s
b = (50 m/s) sin 73.74
b = 48 m/s
Hence,
14i + 48j

Answer:
Average velocity = 1.69 m/s
Average speed = 5.09 m/s
Explanation:
Given that
Horse cover 37 m in 9.1 sec and 18.5 m in 1.8 sec.
As we know that
Average velocity = Displacement / Total time
Average speed = Total distance / Total time
Average velocity:
Average velocity = Displacement / Total time
Total displacement = 37 - 18.5 = 18.5 m
Total time = 9.1 + 1.8 =10.9 s
Average velocity = Displacement / Total time
Average velocity = 18.5 / 10.9
Average velocity = 1.69 m/s
Average speed:
Average speed = Total distance/ Total time
Total distance = 37 + 18.5 = 55.5 m
Total time = 9.1 + 1.8 =10.9 s
Average speed = Total distance/ Total time
Average speed = 55.5 / 10.9
Average speed = 5.09 m/s
