The force pulling a truck downhill is 2,000n, the mass of the truck is 40,000 kg. what is the acceleration?

For this case we have that Newton's second law is given by:

Where:

m: It's the mass

a: Acceleration

F: It's the force

According to the data we have:

Dividing between 40,000 on both sides of the equation:

Thus, the acceleration is

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt

step-by-step explanation:

what grade level is this? need to know so i can look in my old textbooks!
