Question

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

Answer 1

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

$F = m * a$

Where:

m: It's the mass

a: Acceleration

F: It's the force

According to the data we have:

$2,000 = 40,000 * a$

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

$a = \frac {2,000} {40,000}\\a = 0.05$

Thus, the acceleration is $0.05 \frac {m} {s ^ 2}$

Answer:

$0.05 \frac {m} {s ^ 2}$
