Answer:
The amplitude of the subsequent oscillations is 13.3 cm
Explanation:
Given;
mass of the block, m = 1.25 kg
spring constant, k = 17 N/m
speed of the block, v = 49 cm/s = 0.49 m/s
To determine the amplitude of the oscillation.
Apply the principle of conservation of energy;
maximum kinetic energy of the stone when hit = maximum potential energy of spring when displaced

Therefore, the amplitude of the subsequent oscillations is 13.3 cm
Answer:
Secondary voltage of transformer is 905.23 volt
Explanation:
It is given number of turns in primary of transformer 
Number of turns in secondary 
Input voltage equation of the transformer

Here 

For transformer we know that



Therefore secondary voltage of transformer is 905.23 volt
