To develop this problem it will be necessary to apply the concepts related to the frequency of a spring mass system, for which it is necessary that its mathematical function is described as

Here,
k = Spring constant
m = Mass
Our values are given as,


Rearranging to find the spring constant we have that,




Therefore the spring constant is 1.38N/m
Answer:
Its acceleration is positive
Explanation:
As the car is moving in the negative x-direction than after applying brake then there will be a decrease in the acceleration but in the opposite direction.
As decreasing acceleration consider to be negative but the car is moving in negative direction which means increasing acceleration is negative by sign convention but by applying brake acceleration decrease but in opposite direction than it will give positive value of acceleration.
If the ration supplementary angle is 11:7,find the measure of the larger angle larger angle?
v^2-u^2=2 x a x d
25^2-0^2=2 x a x 70
625-0=140 x a
625=140a
a=625/140
a=4.46 m/s^2
im not very sure but i think this is how you do this
The missing value is the 'k' that should appear between '28' and 'g' .
Nobody has a mass of 28g.
My new grandson, who was born yesterday (January 29, 2019), had a mass of 4,039g at birth.
Mother and son are happy and resting comfortably today, in Kfar Tapuach, Samaria, Israel.
