Question

A toy car with a mass of 2.35 kg is pushed with a force of 21.6 N. What is the acceleration of the car? Given Information: Write the given information in the problem. If any units need to be converted,

make that conversion as a part of your given.

Answer 1

9.2m/s²

Step-by-step explanation:

Given parameters:

Mass of the toy car = 2.35kg

Force on the car = 21.6N

Unknown:

Acceleration of the car = ?

Solution:

To solve this problem, we are going to employ the use of Newton's second law of motion.

According to this law "the acceleration of a body is directly proportional to its force and inversely proportional to mass ">

Mathematically;

F = m x a

where F is the force on the car

m is the mass of the car

a is the acceleration of the car

To find the acceleration, we make it the subject of the expression;

a =
`(F)/(m)` =
`(21.6)/(2.35)` = 9.2m/s²
