A net force of 24 N is applied to an object for 5.0 s. The object is pushed a total of 5.2 m. What is the mass of the object? What equations will be used?

Answer 1

To calculate the mass of the object, we can use Newton's second law of motion, which states that the acceleration of an object is directly proportional to the net force applied to it and inversely proportional to its mass. The formula to calculate mass is mass = net force / acceleration.

Step-by-step explanation:

To calculate the mass of the object, we can use Newton's second law of motion, which states that the acceleration of an object is directly proportional to the net force applied to it and inversely proportional to its mass. The formula to calculate mass is:

mass = net force / acceleration

In this case, the net force is 24 N and the acceleration is calculated using the formula:

acceleration = distance / time^2

Given that the object is pushed a total of 5.2 m in 5.0 s, the acceleration is:

acceleration = 5.2 m / (5.0 s)^2

Substituting the values into the mass formula, we have:

mass = 24 N / (5.2 m / (5.0 s)^2)

Simplifying the equation, we can calculate the mass of the object.

Answer 2

S = V0 t + 1/2 a t^2 net distance traveled

5.2 = a/2 * 25

a = 10.4 / 25 = ,416 m / s^2

F = m * a

m = F / a = 24 / .416 = 57.7 N
