HURRY PLEASE SHOW THE WORK TOO!! A truck and a motorbike are at rest and are 900 m apart. They start moving toward, the car accelerates at a rate of 3.2 m/s2 and the motorcycle accelerates at a rate of 5.1 m/s2. At what position will each object pass each other relative to the starting point?

They pass each other at 2415.79 m relative to the starting point.

Explanation:

Let s represent the distance moved by the car.

Since they are 900 m apart, it starts from rest and the truck moves at an acceleration of a = 3.2 m/s², we use

s - s₀ = ut + 1/2at²      u = initial velocity = 0 (since it starts from rest) and s₀ = 900

s = 900 + 1/2 × 3.2 m/s² × t²

s = 900 + 1.6t²

Let s' represent the distance moved by the motorcycle.

Since it starts from rest and the motorcycle moves at an acceleration of a = 5.1 m/s², we use

s' - s₀' = ut + 1/2at²      u = initial velocity = 0 (since it starts from rest) and s₀' = 0 (the starting point of the motorcycle)

s' = 0 + 1/2 × 5.1 m/s² × t²

s' = 2.55t²

At the point where they pass each other, s' = s

2.55t² = 900 + 1.6t²

collecting like terms, we find the time which they meet each other

2.55t² - 1.6t² = 900

0.95t² = 900

t² = 900/0.95

t = √(947.37)

t = 30.78 s

Substituting t into s', we have

s' = 2.55t²

= 2.55(30.78)²

= 2.55(947.37)

= 2415.79 m

So, they pass each other at 2415.79 m relative to the starting point.

when insulating materials rub against each other, they may become electrically charged . electrons , which are negatively charged, may be 'rubbed off' one material and on to the other. the material that gains electrons becomes negatively charged. the material that loses electrons is left with a positive charge.

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.
