maksim [4K]

Answer:

The approximate spring constant is $k = 55533.33 \ N/m$

Explanation:

From the question we are told that

The mass of the person is $m = 68 \ kg$

The dip of the car is $x = 1.2 \ cm = 0.012 \ m$

Generally according to hooks law

$F = k * x$

here the force F is the weight of the person which is mathematically represented as

$F = m * g$

=> $m * g = k * x$

=> $k = \frac{m * g }{x }$

=> $k = \frac{68 * 9.8}{ 0.012}$

=> $k = 55533.33 \ N/m$

A 20kg object acceleration by a force of 200N with coefficient of kineticfriction is 0.4 what is acceleration of the object?

Schach [20]

Answer:

Given - M = 20 kg

k = 0.4

F = 200 N

To find -  acceleration

Solution - 

F= kMA

200 = 0.4 * 20 * acceleration

200 = 8 * a

a = 8/200

a = 0.04 m s²
