65Nm⁻²

Explanation:

Pressure is given by the formulae;

P = F/A  whereby;

P = pressure

F = force

A = area

For the sake of this question, we can replace F with <em>ma</em> because;

F = ma whereby

F = force

M = mass

A = acceleration (in this case due to gravity)

Therefore;

P = ma / A

The cuboid has three (faces) with different areas. Maximum pressure will be applied on the surface with the smallest area (which is 5cm * 10cm);

We will work with the mass in KGS & area in m²

P = 0.0325 * 10 / (0.05 * 0.1)

P = 0.325/0.005

P = 65Nm⁻²

If a 100-n net force acts upon a 50g car, what will the acceleration of the car be
Brrunno [24]

Answer:

2m/s

Explanation:

The formula for acceleration can be found by [ a = f/m ]

We are given the force [ 100N ] and the mass [ 50g ].

We can use these values to solve for the acceleration.

a = 100/50

a = 2m/s

Best of Luck!

A 25 N force stretches a spring 0.280 m. What was the spring constant?
soldi70 [24.7K]

Answer:

the  spring constant is -89.2857 n/m

Explanation:

The computation of the spring constant is shown below:

As we know that

Force in newtons = Spring constant × amount of extension

F = -k × x

where

F = 25 N

And, x = 0.280m

So, the spring constant would 2  

= 25N ÷ 0.280 m

= -89.2857 n/m

Hence the  spring constant is -89.2857 n/m

An acceleration of 2m/s^2 is produced on a body by applying an effort of 50N. calculate mass of the body​
jenyasd209 [6]

Answer:

25 kg

Explanation:

Given,

Acceleration ( a ) = 2 m/s^2

Force ( F ) = 50 N

To find : Mass ( m ) = ?

Formula : -

F = ma

m = F / a

= 50 / 2

m = 25 kg

So, the mass of the body is 25 kg.
