A 3,162-kg truck moving with a velocity of 12 m/s to the East hits a 510-kg parked car. The impact causes the car to be set in m
Musya8 [376]

Given:

The mass of the truck is m1 = 3162 kg

The speed of the truck is v1i = 12 m/s in East

The mass of the parked car is m2 = 510 kg

The speed of car is v2i = 0 m/s

The speed of car after collision is v2f = 24 m/s in East

To find the speed of the truck after collision.

Explanation:

The final velocity of the truck will be

\begin{gathered} m1v1i+m2v2i=m1v1f+m2v2f \\ v1f\text{ =}\frac{m1v1i-m2v2f+m2v2i}{m1} \\ =\frac{3162\times12-510\times24+510\times0}{3162} \\ =8.129\text{ m/s} \end{gathered}

Thus, the speed of the truck after collision is 8.129 m/s

The sources of marine debris and explain why it is a problem with global origins
Lera25 [3.4K]
Marine debris is any trash or litter that ends up in a marine environment. This harms wildlife through entanglement, ingestion, and disturbs the habitat of many species of animals. This becomes a global problem when it is a danger to human health. Nails, syringes, and glass can cause harm to people on the beach. On top of that, trash in the waterway increases the amount of chemicals destroying our water quality.

You and a friend both leave the same restaurant to drive home. You are heading directly west at 30 miles per hour and he or she
steposvetlana [31]

Answer:

\frac{dAB}{dt} = = 50 miles/ hour

Explanation:

let A represent me and B represent my friend

A speed\frac{dOA}{dt}=30 m/hr toward west

B speed\frac{dOB}{dt} =40 m/hr toward south

after 1/2 hr

total distance cover by A =1/2 * 30 miles = 15 miles

total distance by B = 1/2*40 miles = 20 miles

now from figure

AB = \sqrt{(15^2+20^2)} = 25 miles

AB^2 =OA^2+ OB^2

Differentiate above equation

2AB\frac{dAB}{dt} = 2OA\frac{dOA}{dt} +2OB\frac{dOB}{dt}

25*\frac{dAB}{dt} = 15*30 +20*40

\frac{dAB}{dt} = \frac{1250}{25}

\frac{dAB}{dt} = = 50 miles/ hour
