Calculate the rate of acceleration of a 2,000.-kilogram truck if a force of 4,200 N is used to make it start moving forward?
Llana [10]

Answer:

Acceleration, a=2.1\ m/s^2

Explanation:

Given that,

Mass of a truck, m = 2000 kg

Force used to move the truck, F = 4200 N

We need to find the acceleration of the truck. The force acting on the truck is given by the expression as follows :

F = ma

a is the acceleration of the truck

a=\dfrac{F}{m}\\\\a=\dfrac{4200}{2000}\\\\a=2.1\ m/s^2

So, the acceleration of the truck is 2.1\ m/s^2.
