A large wooden crate is pushed along a smooth, frictionless surface by a force of 87 N. The acceleration of the crate is measured to be 2.0 m/s2. What is the mass of the crate?

F = ma,

m = F/a = 87 / 2 = 43.5kg.

To find the mass of the crate, we can use Newton's second law of motion, which states that the force applied to an object is equal to the mass of the object multiplied by its acceleration. Mathematically, it is expressed as follows:

F = m * a

Where:
F = force applied to the object = 87 N
m = mass of the crate (unknown)
a = acceleration of the crate = 2.0 m/s^2

Rearranging the formula, we can solve for the mass of the crate (m):

m = F / a

Plugging in the values given, we have:

m = 87 N / 2.0 m/s^2

m = 43.5 kg

Therefore, the mass of the crate is 43.5 kg.

To find the mass of the crate, you can use Newton's second law of motion equation:

F = ma

where:
F is the force applied on the crate
m is the mass of the crate
a is the acceleration of the crate

In this case, the force applied on the crate is 87 N and the acceleration is 2.0 m/s^2. Rearranging the equation to solve for mass (m), you get:

m = F / a

Plugging in the given values, you can calculate the mass:

m = 87 N / 2.0 m/s^2

m ≈ 43.5 kg

Therefore, the mass of the crate is approximately 43.5 kg.
