Answer:
Net force, F = 7 N
Explanation:
It is given that,
Initial kinetic energy of the car,
Final kinetic energy of the car,
Distance, d = 1 m
We need to find the average net force on the car during this interval. It is given by using the work energy theorem as :
Also, W = F.d d = distance and F = net force
F = 7 Newton
So, the average net force on the car during this interval is 7 newton. Hence, this is the required solution.
Answer:
Part a)
Time period of spring block system is
Part b)
Frequency of spring block system is
Explanation:
As we know that the time period of spring mass system is given as
now we have
M = 12 kg
k = 2200 N/m
now we have
Part b)
As we know that time period of spring block system is inversely dependent on the frequency
so we have
