Answer:
m/s
km/h
mph
Explanation:
speed is measured with distance which does in velocity too that is why I chose this answer
Answer:
The formula for calculating weight is F = m × 9.8 m/s2, where F is the object's weight in Newtons (N) and m is the object's mass in kilograms.
That is red spectrum........................
Kinetic energy is an
expression of the fact that a moving object can do work on anything it hits; it
quantifies the amount of work the object could do as a result of its motion. It
can be calculated as:
KE
= mv^2 /2
We
calculate the problem as follows:
KE
= mv^2 /2
400
= m(20)^2 / 2

= 2 kg</span>
