In a launch speed formula vx = d over t, vx is acceleration, d is distance, and t is time.

V of x is the velocity on the x graph so it is false

Hope it helps

False

Explanation:

Vx can't be acceleration because acceleration is velocity over time not distance over time (the equation for speed)

firearm identification is the process of analyzing the bullets and cartridge cases left at a crime scene to determine if they came from a particular firearm. marks on the bullets and cartridges may be common to every firearm of that type. these are called class characteristics.

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
